Download JAR files tagged by after with all dependencies

GlassFish build depends on properly functioning several custom lifecycle mappings and artifact handlers. Because these are necessary to resolve dependencies and to run "gf:run" goal and etc., it is critical that these extensions be made available to Maven early on during Maven execution. This definition was originally in maven-glassfish-plugin, which was integrated into Maven POM through <plugin>/<extensions>true marking, but after a series of debugging to resolve artifact resolution failure problems, it turns out that that doesn't cause Maven to load components early enough. I tried to circumbent the prolem by also registering the maven-glassfish-plugin as an extension module (via <build>/<extensions/<extension>), but that apparently confuses Maven to no end --- I get build errors like this: [INFO] Internal error in the plugin manager executing goal 'org.apache.maven.plugins:maven-jar-plugin:2.1:jar': Unable to find the mojo 'org.apache.maven.plugins:maven-jar-plugin:2.1:jar' in the plugin 'org.apache.maven.plugins:maven-jar-plugin' This is obviously one of the problematic areas of Maven, so to avoid doing hack over hack, I'm simply moving the component definitions to its own module.

Performs a grid search of parameter pairs for the a classifier (Y-axis, default is LinearRegression with the "Ridge" parameter) and the PLSFilter (X-axis, "# of Components") and chooses the best pair found for the actual predicting. The initial grid is worked on with 2-fold CV to determine the values of the parameter pairs for the selected type of evaluation (e.g., accuracy). The best point in the grid is then taken and a 10-fold CV is performed with the adjacent parameter pairs. If a better pair is found, then this will act as new center and another 10-fold CV will be performed (kind of hill-climbing). This process is repeated until no better pair is found or the best pair is on the border of the grid. In case the best pair is on the border, one can let GridSearch automatically extend the grid and continue the search. Check out the properties 'gridIsExtendable' (option '-extend-grid') and 'maxGridExtensions' (option '-max-grid-extensions <num>'). GridSearch can handle doubles, integers (values are just cast to int) and booleans (0 is false, otherwise true). float, char and long are supported as well. The best filter/classifier setup can be accessed after the buildClassifier call via the getBestFilter/getBestClassifier methods. Note on the implementation: after the data has been passed through the filter, a default NumericCleaner filter is applied to the data in order to avoid numbers that are getting too small and might produce NaNs in other schemes.

This is an implementation of the Neural Gas algorithm on distance data (Relational Neural Gas) for unsupervised clustering. We recommend that you use the functions provided by the RelationalNeuralGas class for your purposes. All other classes and functions are utilities which are used by this central class. In particular, you can use RelationalNeuralGas.train() to obtain a RNGModel (i.e. a clustering of your data), and subsequently you can use RelationalNeuralGas.getAssignments() to obtain the resulting cluster assignments, and RelationalNeuralGas.classify() to cluster new points which are not part of the training data set. The underlying scientific work is summarized nicely in the dissertation "Topographic Mapping of Dissimilarity Datasets" by Alexander Hasenfuss (2009). The basic properties of an Relational Neural Gas algorithm are the following: 1.) It is relational: The data is represented only in terms of a pairwise distance matrix. 2.) It is a clustering method: The algorithm provides a clustering model, that is: After calculation, each data point should be assigned to a cluster (for this package here we only consider hard clustering, that is: each data point is assigned to exactly one cluster). 3.) It is a vector quantization method: Each cluster corresponds to a prototype, which is in the center of the cluster and data points are assigned to the cluster if and only if they are closest to this particular prototype. 4.) It is rank-based: The updates of the prototypes depend only on the distance ranking, not on the absolute value of the distances.

GroupDocs.Editor for Java is a powerful document editing API using HTML. API can be used with any external, opensource or paid HTML editor. Editor API will process to load documents, convert it to HTML, provide HTML to external UI and then save HTML to original document after manipulation. It can also be used to generate different PDF files, Microsoft Word (DOC, DOCX), Excel spreadsheets (XLS, XSLSX), PowerPoint presentations (PPT, PPTX) and TXT documents. Manipulate Using HTML: Load Document Edit content using HTML Edit styles Perform Editor operations Convert back to supported file Document Editor is a computer program for editing HTML, the markup of a webpage. Although the HTML markup of a web page can be written with any text editor, specialized HTML editors can offer convenience and added functionality. For example, many HTML editors handle not only HTML, but also related technologies such as CSS, XML and JavaScript or ECMAScript. In some cases they also manage communication with remote web servers via FTP and WebDAV, and version control systems such as Subversion or Git. Many word processing, graphic design and page layout programs that are not dedicated to web design, such as Microsoft Word or Quark XPress, also have the ability to function as HTML editors.

# Leiningen plugin to verify a provider [version 2.2.14+, 3.0.3+] Leiningen plugin for verifying pacts against a provider. The plugin provides a `pact-verify` task which will verify all configured pacts against your provider. ## To Use It ### 1. Add the plugin to your project plugins, preferably in it&apos;s own profile. ```clojure :profiles { :pact { :plugins [[au.com.dius/pact-jvm-provider-lein_2.11 &quot;3.2.11&quot; :exclusions [commons-logging]]] :dependencies [[ch.qos.logback/logback-core &quot;1.1.3&quot;] [ch.qos.logback/logback-classic &quot;1.1.3&quot;] [org.apache.httpcomponents/httpclient &quot;4.4.1&quot;]] }}} ``` ### 2. Define the pacts between your consumers and providers You define all the providers and consumers within the `:pact` configuration element of your project. ```clojure :pact { :service-providers { ; You can define as many as you need, but each must have a unique name :provider1 { ; All the provider properties are optional, and have sensible defaults (shown below) :protocol &quot;http&quot; :host &quot;localhost&quot; :port 8080 :path &quot;/&quot; :has-pact-with { ; Again, you can define as many consumers for each provider as you need, but each must have a unique name :consumer1 { ; pact file can be either a path or an URL :pact-file &quot;path/to/provider1-consumer1-pact.json&quot; } } } } } ``` ### 3. Execute `lein with-profile pact pact-verify` You will have to have your provider running for this to pass. ## Enabling insecure SSL For providers that are running on SSL with self-signed certificates, you need to enable insecure SSL mode by setting `:insecure true` on the provider. ```clojure :pact { :service-providers { :provider1 { :protocol &quot;https&quot; :host &quot;localhost&quot; :port 8443 :insecure true :has-pact-with { :consumer1 { :pact-file &quot;path/to/provider1-consumer1-pact.json&quot; } } } } } ``` ## Specifying a custom trust store For environments that are running their own certificate chains: ```clojure :pact { :service-providers { :provider1 { :protocol &quot;https&quot; :host &quot;localhost&quot; :port 8443 :trust-store &quot;relative/path/to/trustStore.jks&quot; :trust-store-password &quot;changeme&quot; :has-pact-with { :consumer1 { :pact-file &quot;path/to/provider1-consumer1-pact.json&quot; } } } } } ``` `:trust-store` is relative to the current working (build) directory. `:trust-store-password` defaults to `changeit`. NOTE: The hostname will still be verified against the certificate. ## Modifying the requests before they are sent Sometimes you may need to add things to the requests that can&apos;t be persisted in a pact file. Examples of these would be authentication tokens, which have a small life span. The Leiningen plugin provides a request filter that can be set to an anonymous function on the provider that will be called before the request is made. This function will receive the HttpRequest object as a parameter. ```clojure :pact { :service-providers { :provider1 { ; function that adds an Authorization header to each request :request-filter #(.addHeader % &quot;Authorization&quot; &quot;oauth-token eyJhbGciOiJSUzI1NiIsIm...&quot;) :has-pact-with { :consumer1 { :pact-file &quot;path/to/provider1-consumer1-pact.json&quot; } } } } } ``` __*Important Note:*__ You should only use this feature for things that can not be persisted in the pact file. By modifying the request, you are potentially modifying the contract from the consumer tests! ## Modifying the HTTP Client Used The default HTTP client is used for all requests to providers (created with a call to `HttpClients.createDefault()`). This can be changed by specifying a function assigned to `:create-client` on the provider that returns a `CloseableHttpClient`. The function will receive the provider info as a parameter. ## Turning off URL decoding of the paths in the pact file [version 3.3.3+] By default the paths loaded from the pact file will be decoded before the request is sent to the provider. To turn this behaviour off, set the system property `pact.verifier.disableUrlPathDecoding` to `true`. __*Important Note:*__ If you turn off the url path decoding, you need to ensure that the paths in the pact files are correctly encoded. The verifier will not be able to make a request with an invalid encoded path. ## Plugin Properties The following plugin options can be specified on the command line: |Property|Description| |--------|-----------| |:pact.showStacktrace|This turns on stacktrace printing for each request. It can help with diagnosing network errors| |:pact.showFullDiff|This turns on displaying the full diff of the expected versus actual bodies [version 3.3.6+]| |:pact.filter.consumers|Comma seperated list of consumer names to verify| |:pact.filter.description|Only verify interactions whose description match the provided regular expression| |:pact.filter.providerState|Only verify interactions whose provider state match the provided regular expression. An empty string matches interactions that have no state| |:pact.verifier.publishResults|Publishing of verification results will be skipped unless this property is set to &apos;true&apos; [version 3.5.18+]| |:pact.matching.wildcard|Enables matching of map values ignoring the keys when this property is set to &apos;true&apos;| Example, to run verification only for a particular consumer: ``` $ lein with-profile pact pact-verify :pact.filter.consumers=:consumer2 ``` ## Provider States For each provider you can specify a state change URL to use to switch the state of the provider. This URL will receive the `providerState` description from the pact file before each interaction via a POST. The `:state-change-uses-body` controls if the state is passed in the request body or as a query parameter. These values can be set at the provider level, or for a specific consumer. Consumer values take precedent if both are given. ```clojure :pact { :service-providers { :provider1 { :state-change-url &quot;http://localhost:8080/tasks/pactStateChange&quot; :state-change-uses-body false ; defaults to true :has-pact-with { :consumer1 { :pact-file &quot;path/to/provider1-consumer1-pact.json&quot; } } } } } ``` If the `:state-change-uses-body` is not specified, or is set to true, then the provider state description will be sent as JSON in the body of the request. If it is set to false, it will passed as a query parameter. As for normal requests (see Modifying the requests before they are sent), a state change request can be modified before it is sent. Set `:state-change-request-filter` to an anonymous function on the provider that will be called before the request is made. #### Returning values that can be injected (3.6.11+) You can have values from the provider state callbacks be injected into most places (paths, query parameters, headers, bodies, etc.). This works by using the V3 spec generators with provider state callbacks that return values. One example of where this would be useful is API calls that require an ID which would be auto-generated by the database on the provider side, so there is no way to know what the ID would be beforehand. There are methods on the consumer DSLs that can provider an expression that contains variables (like &apos;/api/user/${id}&apos; for the path). The provider state callback can then return a map for values, and the `id` attribute from the map will be expanded in the expression. For URL callbacks, the values need to be returned as JSON in the response body. ## Filtering the interactions that are verified You can filter the interactions that are run using three properties: `:pact.filter.consumers`, `:pact.filter.description` and `:pact.filter.providerState`. Adding `:pact.filter.consumers=:consumer1,:consumer2` to the command line will only run the pact files for those consumers (consumer1 and consumer2). Adding `:pact.filter.description=a request for payment.*` will only run those interactions whose descriptions start with &apos;a request for payment&apos;. `:pact.filter.providerState=.*payment` will match any interaction that has a provider state that ends with payment, and `:pact.filter.providerState=` will match any interaction that does not have a provider state. ## Starting and shutting down your provider For the pact verification to run, the provider needs to be running. Leiningen provides a `do` task that can chain tasks together. So, by creating a `start-app` and `terminate-app` alias, you could so something like: $ lein with-profile pact do start-app, pact-verify, terminate-app However, if the pact verification fails the build will abort without running the `terminate-app` task. To have the start and terminate tasks always run regardless of the state of the verification, you can assign them to `:start-provider-task` and `:terminate-provider-task` on the provider. ```clojure :aliases {&quot;start-app&quot; ^{:doc &quot;Starts the app&quot;} [&quot;tasks to start app ...&quot;] ; insert tasks to start the app here &quot;terminate-app&quot; ^{:doc &quot;Kills the app&quot;} [&quot;tasks to terminate app ...&quot;] ; insert tasks to stop the app here } :pact { :service-providers { :provider1 { :start-provider-task &quot;start-app&quot; :terminate-provider-task &quot;terminate-app&quot; :has-pact-with { :consumer1 { :pact-file &quot;path/to/provider1-consumer1-pact.json&quot; } } } } } ``` Then you can just run: $ lein with-profile pact pact-verify and the `start-app` and `terminate-app` tasks will run before and after the provider verification. ## Specifying the provider hostname at runtime [3.0.4+] If you need to calculate the provider hostname at runtime (for instance it is run as a new docker container or AWS instance), you can give an anonymous function as the provider host that returns the host name. The function will receive the provider information as a parameter. ```clojure :pact { :service-providers { :provider1 { :host #(calculate-host-name %) :has-pact-with { :consumer1 { :pact-file &quot;path/to/provider1-consumer1-pact.json&quot; } } } } } ```

If it is set to false, it will passed as a query parameter. As for normal requests (see Modifying the requests before they are sent), a state change request can be modified before it is sent. Set `:state-change-request-filter` to an anonymous function on the provider that will be called before the request is made. ## Filtering the interactions that are verified You can filter the interactions that are run using three properties: `:pact.filter.consumers`, `:pact.filter.description` and `:pact.filter.providerState`. Adding `:pact.filter.consumers=consumer1,consumer2` to the command line will only run the pact files for those consumers (consumer1 and consumer2). Adding `:pact.filter.description=a request for payment.*` will only run those interactions whose descriptions start with &apos;a request for payment&apos;. `:pact.filter.providerState=.*payment` will match any interaction that has a provider state that ends with payment, and `:pact.filter.providerState=` will match any interaction that does not have a provider state. ## Starting and shutting down your provider For the pact verification to run, the provider needs to be running. Leiningen provides a `do` task that can chain tasks together. So, by creating a `start-app` and `terminate-app` alias, you could so something like: $ lein with-profile pact do start-app, pact-verify, terminate-app However, if the pact verification fails the build will abort without running the `terminate-app` task. To have the start and terminate tasks always run regardless of the state of the verification, you can assign them to `:start-provider-task` and `:terminate-provider-task` on the provider. ```clojure :aliases {&quot;start-app&quot; ^{:doc &quot;Starts the app&quot;} [&quot;tasks to start app ...&quot;] ; insert tasks to start the app here &quot;terminate-app&quot; ^{:doc &quot;Kills the app&quot;} [&quot;tasks to terminate app ...&quot;] ; insert tasks to stop the app here } :pact { :service-providers { :provider1 { :start-provider-task &quot;start-app&quot; :terminate-provider-task &quot;terminate-app&quot; :has-pact-with { :consumer1 { :pact-file &quot;path/to/provider1-consumer1-pact.json&quot; } } } } } ``` Then you can just run: $ lein with-profile pact pact-verify and the `start-app` and `terminate-app` tasks will run before and after the provider verification. ## Specifying the provider hostname at runtime [3.0.4+] If you need to calculate the provider hostname at runtime (for instance it is run as a new docker container or AWS instance), you can give an anonymous function as the provider host that returns the host name. The function will receive the provider information as a parameter. ```clojure :pact { :service-providers { :provider1 { :host #(calculate-host-name %) :has-pact-with { :consumer1 { :pact-file &quot;path/to/provider1-consumer1-pact.json&quot; } } } } } ```

# Leiningen plugin to verify a provider [version 2.2.14+, 3.0.3+] Leiningen plugin for verifying pacts against a provider. The plugin provides a `pact-verify` task which will verify all configured pacts against your provider. ## To Use It ### 1. Add the plugin to your project plugins, preferably in it's own profile. ```clojure :profiles { :pact { :plugins [[au.com.dius/pact-jvm-provider-lein_2.11 "3.0.3" :exclusions [commons-logging]]] :dependencies [[ch.qos.logback/logback-core "1.1.3"] [ch.qos.logback/logback-classic "1.1.3"] [org.apache.httpcomponents/httpclient "4.4.1"]] }}} ``` ### 2. Define the pacts between your consumers and providers You define all the providers and consumers within the `:pact` configuration element of your project. ```clojure :pact { :service-providers { ; You can define as many as you need, but each must have a unique name :provider1 { ; All the provider properties are optional, and have sensible defaults (shown below) :protocol "http" :host "localhost" :port 8080 :path "/" :has-pact-with { ; Again, you can define as many consumers for each provider as you need, but each must have a unique name :consumer1 { ; pact file can be either a path or an URL :pact-file "path/to/provider1-consumer1-pact.json" } } } } } ``` ### 3. Execute `lein with-profile pact pact-verify` You will have to have your provider running for this to pass. ## Enabling insecure SSL For providers that are running on SSL with self-signed certificates, you need to enable insecure SSL mode by setting `:insecure true` on the provider. ```clojure :pact { :service-providers { :provider1 { :protocol "https" :host "localhost" :port 8443 :insecure true :has-pact-with { :consumer1 { :pact-file "path/to/provider1-consumer1-pact.json" } } } } } ``` ## Specifying a custom trust store For environments that are running their own certificate chains: ```clojure :pact { :service-providers { :provider1 { :protocol "https" :host "localhost" :port 8443 :trust-store "relative/path/to/trustStore.jks" :trust-store-password "changeme" :has-pact-with { :consumer1 { :pact-file "path/to/provider1-consumer1-pact.json" } } } } } ``` `:trust-store` is relative to the current working (build) directory. `:trust-store-password` defaults to `changeit`. NOTE: The hostname will still be verified against the certificate. ## Modifying the requests before they are sent Sometimes you may need to add things to the requests that can't be persisted in a pact file. Examples of these would be authentication tokens, which have a small life span. The Leiningen plugin provides a request filter that can be set to an anonymous function on the provider that will be called before the request is made. This function will receive the HttpRequest object as a parameter. ```clojure :pact { :service-providers { :provider1 { ; function that adds an Authorization header to each request :request-filter #(.addHeader % "Authorization" "oauth-token eyJhbGciOiJSUzI1NiIsIm...") :has-pact-with { :consumer1 { :pact-file "path/to/provider1-consumer1-pact.json" } } } } } ``` __*Important Note:*__ You should only use this feature for things that can not be persisted in the pact file. By modifying the request, you are potentially modifying the contract from the consumer tests! ## Modifying the HTTP Client Used The default HTTP client is used for all requests to providers (created with a call to `HttpClients.createDefault()`). This can be changed by specifying a function assigned to `:create-client` on the provider that returns a `CloseableHttpClient`. The function will receive the provider info as a parameter. ## Plugin Properties The following plugin options can be specified on the command line: |Property|Description| |--------|-----------| |:pact.showStacktrace|This turns on stacktrace printing for each request. It can help with diagnosing network errors| |:pact.filter.consumers|Comma seperated list of consumer names to verify| |:pact.filter.description|Only verify interactions whose description match the provided regular expression| |:pact.filter.providerState|Only verify interactions whose provider state match the provided regular expression. An empty string matches interactions that have no state| Example, to run verification only for a particular consumer: ``` $ lein with-profile pact pact-verify :pact.filter.consumers=consumer2 ``` ## Provider States For each provider you can specify a state change URL to use to switch the state of the provider. This URL will receive the `providerState` description from the pact file before each interaction via a POST. The `:state-change-uses-body` controls if the state is passed in the request body or as a query parameter. These values can be set at the provider level, or for a specific consumer. Consumer values take precedent if both are given. ```clojure :pact { :service-providers { :provider1 { :state-change-url "http://localhost:8080/tasks/pactStateChange" :state-change-uses-body false ; defaults to true :has-pact-with { :consumer1 { :pact-file "path/to/provider1-consumer1-pact.json" } } } } } ``` If the `:state-change-uses-body` is not specified, or is set to true, then the provider state description will be sent as JSON in the body of the request. If it is set to false, it will passed as a query parameter. As for normal requests (see Modifying the requests before they are sent), a state change request can be modified before it is sent. Set `:state-change-request-filter` to an anonymous function on the provider that will be called before the request is made. ## Filtering the interactions that are verified You can filter the interactions that are run using three properties: `:pact.filter.consumers`, `:pact.filter.description` and `:pact.filter.providerState`. Adding `:pact.filter.consumers=consumer1,consumer2` to the command line will only run the pact files for those consumers (consumer1 and consumer2). Adding `:pact.filter.description=a request for payment.*` will only run those interactions whose descriptions start with 'a request for payment'. `:pact.filter.providerState=.*payment` will match any interaction that has a provider state that ends with payment, and `:pact.filter.providerState=` will match any interaction that does not have a provider state. ## Starting and shutting down your provider For the pact verification to run, the provider needs to be running. Leiningen provides a `do` task that can chain tasks together. So, by creating a `start-app` and `terminate-app` alias, you could so something like: $ lein with-profile pact do start-app, pact-verify, terminate-app However, if the pact verification fails the build will abort without running the `terminate-app` task. To have the start and terminate tasks always run regardless of the state of the verification, you can assign them to `:start-provider-task` and `:terminate-provider-task` on the provider. ```clojure :aliases {"start-app" ^{:doc "Starts the app"} ["tasks to start app ..."] ; insert tasks to start the app here "terminate-app" ^{:doc "Kills the app"} ["tasks to terminate app ..."] ; insert tasks to stop the app here } :pact { :service-providers { :provider1 { :start-provider-task "start-app" :terminate-provider-task "terminate-app" :has-pact-with { :consumer1 { :pact-file "path/to/provider1-consumer1-pact.json" } } } } } ``` Then you can just run: $ lein with-profile pact pact-verify and the `start-app` and `terminate-app` tasks will run before and after the provider verification. ## Specifying the provider hostname at runtime [3.0.4+] If you need to calculate the provider hostname at runtime (for instance it is run as a new docker container or AWS instance), you can give an anonymous function as the provider host that returns the host name. The function will receive the provider information as a parameter. ```clojure :pact { :service-providers { :provider1 { :host #(calculate-host-name %) :has-pact-with { :consumer1 { :pact-file "path/to/provider1-consumer1-pact.json" } } } } } ```

Maven plugin to verify a provider ================================= Maven plugin for verifying pacts against a provider. The Maven plugin provides a `verify` goal which will verify all configured pacts against your provider. ## To Use It ### 1. Add the pact-jvm-provider-maven plugin to your `build` section of your pom file. ```xml &lt;build&gt; [...] &lt;plugins&gt; [...] &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.11&lt;/version&gt; &lt;/plugin&gt; [...] &lt;/plugins&gt; [...] &lt;/build&gt; ``` ### 2. Define the pacts between your consumers and providers You define all the providers and consumers within the configuration element of the maven plugin. ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.11&lt;/version&gt; &lt;configuration&gt; &lt;serviceProviders&gt; &lt;!-- You can define as many as you need, but each must have a unique name --&gt; &lt;serviceProvider&gt; &lt;name&gt;provider1&lt;/name&gt; &lt;!-- All the provider properties are optional, and have sensible defaults (shown below) --&gt; &lt;protocol&gt;http&lt;/protocol&gt; &lt;host&gt;localhost&lt;/host&gt; &lt;port&gt;8080&lt;/port&gt; &lt;path&gt;/&lt;/path&gt; &lt;consumers&gt; &lt;!-- Again, you can define as many consumers for each provider as you need, but each must have a unique name --&gt; &lt;consumer&gt; &lt;name&gt;consumer1&lt;/name&gt; &lt;!-- currently supports a file path using pactFile or a URL using pactUrl --&gt; &lt;pactFile&gt;path/to/provider1-consumer1-pact.json&lt;/pactFile&gt; &lt;/consumer&gt; &lt;/consumers&gt; &lt;/serviceProvider&gt; &lt;/serviceProviders&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` ### 3. Execute `mvn pact:verify` You will have to have your provider running for this to pass. ## Verifying all pact files in a directory for a provider You can specify a directory that contains pact files, and the Pact plugin will scan for all pact files that match that provider and define a consumer for each pact file in the directory. Consumer name is read from contents of pact file. ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.11&lt;/version&gt; &lt;configuration&gt; &lt;serviceProviders&gt; &lt;!-- You can define as many as you need, but each must have a unique name --&gt; &lt;serviceProvider&gt; &lt;name&gt;provider1&lt;/name&gt; &lt;!-- All the provider properties are optional, and have sensible defaults (shown below) --&gt; &lt;protocol&gt;http&lt;/protocol&gt; &lt;host&gt;localhost&lt;/host&gt; &lt;port&gt;8080&lt;/port&gt; &lt;path&gt;/&lt;/path&gt; &lt;pactFileDirectory&gt;path/to/pacts&lt;/pactFileDirectory&gt; &lt;/serviceProvider&gt; &lt;/serviceProviders&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` ### Verifying all pact files from multiple directories for a provider [3.5.18+] If you want to specify multiple directories, you can use `pactFileDirectories`. The plugin will only fail the build if no pact files are loaded after processing all the directories in the list. ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.18&lt;/version&gt; &lt;configuration&gt; &lt;serviceProviders&gt; &lt;serviceProvider&gt; &lt;name&gt;provider1&lt;/name&gt; &lt;pactFileDirectories&gt; &lt;pactFileDirectory&gt;path/to/pacts1&lt;/pactFileDirectory&gt; &lt;pactFileDirectory&gt;path/to/pacts2&lt;/pactFileDirectory&gt; &lt;/pactFileDirectories&gt; &lt;/serviceProvider&gt; &lt;/serviceProviders&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` ## Enabling insecure SSL For providers that are running on SSL with self-signed certificates, you need to enable insecure SSL mode by setting `&lt;insecure&gt;true&lt;/insecure&gt;` on the provider. ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.11&lt;/version&gt; &lt;configuration&gt; &lt;serviceProviders&gt; &lt;serviceProvider&gt; &lt;name&gt;provider1&lt;/name&gt; &lt;pactFileDirectory&gt;path/to/pacts&lt;/pactFileDirectory&gt; &lt;insecure&gt;true&lt;/insecure&gt; &lt;/serviceProvider&gt; &lt;/serviceProviders&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` ## Specifying a custom trust store For environments that are running their own certificate chains: ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.11&lt;/version&gt; &lt;configuration&gt; &lt;serviceProviders&gt; &lt;serviceProvider&gt; &lt;name&gt;provider1&lt;/name&gt; &lt;pactFileDirectory&gt;path/to/pacts&lt;/pactFileDirectory&gt; &lt;trustStore&gt;relative/path/to/trustStore.jks&lt;/trustStore&gt; &lt;trustStorePassword&gt;changeit&lt;/trustStorePassword&gt; &lt;/serviceProvider&gt; &lt;/serviceProviders&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` `trustStore` is either relative to the current working (build) directory. `trustStorePassword` defaults to `changeit`. NOTE: The hostname will still be verified against the certificate. ## Modifying the requests before they are sent Sometimes you may need to add things to the requests that can&apos;t be persisted in a pact file. Examples of these would be authentication tokens, which have a small life span. The Pact Maven plugin provides a request filter that can be set to a Groovy script on the provider that will be called before the request is made. This script will receive the HttpRequest bound to a variable named `request` prior to it being executed. ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.11&lt;/version&gt; &lt;configuration&gt; &lt;serviceProviders&gt; &lt;serviceProvider&gt; &lt;name&gt;provider1&lt;/name&gt; &lt;requestFilter&gt; // This is a Groovy script that adds an Authorization header to each request request.addHeader(&apos;Authorization&apos;, &apos;oauth-token eyJhbGciOiJSUzI1NiIsIm...&apos;) &lt;/requestFilter&gt; &lt;consumers&gt; &lt;consumer&gt; &lt;name&gt;consumer1&lt;/name&gt; &lt;pactFile&gt;path/to/provider1-consumer1-pact.json&lt;/pactFile&gt; &lt;/consumer&gt; &lt;/consumers&gt; &lt;/serviceProvider&gt; &lt;/serviceProviders&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` __*Important Note:*__ You should only use this feature for things that can not be persisted in the pact file. By modifying the request, you are potentially modifying the contract from the consumer tests! ## Modifying the HTTP Client Used The default HTTP client is used for all requests to providers (created with a call to `HttpClients.createDefault()`). This can be changed by specifying a closure assigned to createClient on the provider that returns a CloseableHttpClient. For example: ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.11&lt;/version&gt; &lt;configuration&gt; &lt;serviceProviders&gt; &lt;serviceProvider&gt; &lt;name&gt;provider1&lt;/name&gt; &lt;createClient&gt; // This is a Groovy script that will enable the client to accept self-signed certificates import org.apache.http.ssl.SSLContextBuilder import org.apache.http.conn.ssl.NoopHostnameVerifier import org.apache.http.impl.client.HttpClients HttpClients.custom().setSSLHostnameVerifier(new NoopHostnameVerifier()) .setSslcontext(new SSLContextBuilder().loadTrustMaterial(null, { x509Certificates, s -&gt; true }) .build()) .build() &lt;/createClient&gt; &lt;consumers&gt; &lt;consumer&gt; &lt;name&gt;consumer1&lt;/name&gt; &lt;pactFile&gt;path/to/provider1-consumer1-pact.json&lt;/pactFile&gt; &lt;/consumer&gt; &lt;/consumers&gt; &lt;/serviceProvider&gt; &lt;/serviceProviders&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` ## Turning off URL decoding of the paths in the pact file By default the paths loaded from the pact file will be decoded before the request is sent to the provider. To turn this behaviour off, set the system property `pact.verifier.disableUrlPathDecoding` to `true`. __*Important Note:*__ If you turn off the url path decoding, you need to ensure that the paths in the pact files are correctly encoded. The verifier will not be able to make a request with an invalid encoded path. ## Plugin Properties The following plugin properties can be specified with `-Dproperty=value` on the command line or in the configuration section: |Property|Description| |--------|-----------| |pact.showStacktrace|This turns on stacktrace printing for each request. It can help with diagnosing network errors| |pact.showFullDiff|This turns on displaying the full diff of the expected versus actual bodies| |pact.filter.consumers|Comma separated list of consumer names to verify| |pact.filter.description|Only verify interactions whose description match the provided regular expression| |pact.filter.providerState|Only verify interactions whose provider state match the provided regular expression. An empty string matches interactions that have no state| |pact.verifier.publishResults|Publishing of verification results will be skipped unless this property is set to &apos;true&apos; [version 3.5.18+]| |pact.matching.wildcard|Enables matching of map values ignoring the keys when this property is set to &apos;true&apos;| Example in the configuration section: ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.11&lt;/version&gt; &lt;configuration&gt; &lt;serviceProviders&gt; &lt;serviceProvider&gt; &lt;name&gt;provider1&lt;/name&gt; &lt;consumers&gt; &lt;consumer&gt; &lt;name&gt;consumer1&lt;/name&gt; &lt;pactFile&gt;path/to/provider1-consumer1-pact.json&lt;/pactFile&gt; &lt;/consumer&gt; &lt;/consumers&gt; &lt;/serviceProvider&gt; &lt;/serviceProviders&gt; &lt;configuration&gt; &lt;pact.showStacktrace&gt;true&lt;/pact.showStacktrace&gt; &lt;/configuration&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` ## Provider States For each provider you can specify a state change URL to use to switch the state of the provider. This URL will receive the providerState description and parameters from the pact file before each interaction via a POST. The stateChangeUsesBody controls if the state is passed in the request body or as query parameters. These values can be set at the provider level, or for a specific consumer. Consumer values take precedent if both are given. ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.11&lt;/version&gt; &lt;configuration&gt; &lt;serviceProviders&gt; &lt;serviceProvider&gt; &lt;name&gt;provider1&lt;/name&gt; &lt;stateChangeUrl&gt;http://localhost:8080/tasks/pactStateChange&lt;/stateChangeUrl&gt; &lt;stateChangeUsesBody&gt;false&lt;/stateChangeUsesBody&gt; &lt;!-- defaults to true --&gt; &lt;consumers&gt; &lt;consumer&gt; &lt;name&gt;consumer1&lt;/name&gt; &lt;pactFile&gt;path/to/provider1-consumer1-pact.json&lt;/pactFile&gt; &lt;stateChangeUrl&gt;http://localhost:8080/tasks/pactStateChangeForConsumer1&lt;/stateChangeUrl&gt; &lt;stateChangeUsesBody&gt;false&lt;/stateChangeUsesBody&gt; &lt;!-- defaults to true --&gt; &lt;/consumer&gt; &lt;/consumers&gt; &lt;/serviceProvider&gt; &lt;/serviceProviders&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` If the `stateChangeUsesBody` is not specified, or is set to true, then the provider state description and parameters will be sent as JSON in the body of the request. If it is set to false, they will passed as query parameters. As for normal requests (see Modifying the requests before they are sent), a state change request can be modified before it is sent. Set `stateChangeRequestFilter` to a Groovy script on the provider that will be called before the request is made. #### Teardown calls for state changes You can enable teardown state change calls by setting the property `&lt;stateChangeTeardown&gt;true&lt;/stateChangeTeardown&gt;` on the provider. This will add an `action` parameter to the state change call. The setup call before the test will receive `action=setup`, and then a teardown call will be made afterwards to the state change URL with `action=teardown`. ## Verifying pact files from a pact broker You can setup your build to validate against the pacts stored in a pact broker. The pact plugin will query the pact broker for all consumers that have a pact with the provider based on its name. To use it, just configure the `pactBrokerUrl` or `pactBroker` value for the provider with the base URL to the pact broker. For example: ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.11&lt;/version&gt; &lt;configuration&gt; &lt;serviceProviders&gt; &lt;serviceProvider&gt; &lt;name&gt;provider1&lt;/name&gt; &lt;stateChangeUrl&gt;http://localhost:8080/tasks/pactStateChange&lt;/stateChangeUrl&gt; &lt;pactBrokerUrl&gt;http://pact-broker:5000/&lt;/pactBrokerUrl&gt; &lt;/serviceProvider&gt; &lt;/serviceProviders&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` ### Verifying pacts from an authenticated pact broker If your pact broker requires authentication (basic authentication is only supported), you can configure the username and password to use by configuring the `authentication` element of the `pactBroker` element of your provider. For example: ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.11&lt;/version&gt; &lt;configuration&gt; &lt;serviceProviders&gt; &lt;serviceProvider&gt; &lt;name&gt;provider1&lt;/name&gt; &lt;stateChangeUrl&gt;http://localhost:8080/tasks/pactStateChange&lt;/stateChangeUrl&gt; &lt;pactBroker&gt; &lt;url&gt;http://pactbroker:1234&lt;/url&gt; &lt;authentication&gt; &lt;username&gt;test&lt;/username&gt; &lt;password&gt;test&lt;/password&gt; &lt;/authentication&gt; &lt;/pactBroker&gt; &lt;/serviceProvider&gt; &lt;/serviceProviders&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` #### Using the Maven servers configuration [version 3.5.6+] From version 3.5.6, you can use the servers setup in the Maven settings. To do this, setup a server as per the [Maven Server Settings](https://maven.apache.org/settings.html#Servers). Then set the server ID in the pact broker configuration in your POM. ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.6&lt;/version&gt; &lt;configuration&gt; &lt;serviceProviders&gt; &lt;serviceProvider&gt; &lt;name&gt;provider1&lt;/name&gt; &lt;stateChangeUrl&gt;http://localhost:8080/tasks/pactStateChange&lt;/stateChangeUrl&gt; &lt;pactBroker&gt; &lt;url&gt;http://pactbroker:1234&lt;/url&gt; &lt;serverId&gt;test-pact-broker&lt;/serverId&gt; &lt;!-- This must match the server id in the maven settings --&gt; &lt;/pactBroker&gt; &lt;/serviceProvider&gt; &lt;/serviceProviders&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` ### Verifying pacts from an pact broker that match particular tags If your pacts in your pact broker have been tagged, you can set the tags to fetch by configuring the `tags` element of the `pactBroker` element of your provider. For example: ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.11&lt;/version&gt; &lt;configuration&gt; &lt;serviceProviders&gt; &lt;serviceProvider&gt; &lt;name&gt;provider1&lt;/name&gt; &lt;stateChangeUrl&gt;http://localhost:8080/tasks/pactStateChange&lt;/stateChangeUrl&gt; &lt;pactBroker&gt; &lt;url&gt;http://pactbroker:1234&lt;/url&gt; &lt;tags&gt; &lt;tag&gt;TEST&lt;/tag&gt; &lt;tag&gt;DEV&lt;/tag&gt; &lt;/tags&gt; &lt;/pactBroker&gt; &lt;/serviceProvider&gt; &lt;/serviceProviders&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` This example will fetch and validate the pacts for the TEST and DEV tags. ## Filtering the interactions that are verified You can filter the interactions that are run using three properties: `pact.filter.consumers`, `pact.filter.description` and `pact.filter.providerState`. Adding `-Dpact.filter.consumers=consumer1,consumer2` to the command line or configuration section will only run the pact files for those consumers (consumer1 and consumer2). Adding `-Dpact.filter.description=a request for payment.*` will only run those interactions whose descriptions start with &apos;a request for payment&apos;. `-Dpact.filter.providerState=.*payment` will match any interaction that has a provider state that ends with payment, and `-Dpact.filter.providerState=` will match any interaction that does not have a provider state. ## Not failing the build if no pact files are found [version 3.5.19+] By default, if there are no pact files to verify, the plugin will raise an exception. This is to guard against false positives where the build is passing but nothing has been verified due to mis-configuration. To disable this behaviour, set the `failIfNoPactsFound` parameter to `false`. # Verifying a message provider The Maven plugin has been updated to allow invoking test methods that can return the message contents from a message producer. To use it, set the way to invoke the verification to `ANNOTATED_METHOD`. This will allow the pact verification task to scan for test methods that return the message contents. Add something like the following to your maven pom file: ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.11&lt;/version&gt; &lt;configuration&gt; &lt;serviceProviders&gt; &lt;serviceProvider&gt; &lt;name&gt;messageProvider&lt;/name&gt; &lt;verificationType&gt;ANNOTATED_METHOD&lt;/verificationType&gt; &lt;!-- packagesToScan is optional, but leaving it out will result in the entire test classpath being scanned. Set it to the packages where your annotated test method can be found. --&gt; &lt;packagesToScan&gt; &lt;packageToScan&gt;au.com.example.messageprovider.*&lt;/packageToScan&gt; &lt;/packagesToScan&gt; &lt;consumers&gt; &lt;consumer&gt; &lt;name&gt;consumer1&lt;/name&gt; &lt;pactFile&gt;path/to/messageprovider-consumer1-pact.json&lt;/pactFile&gt; &lt;/consumer&gt; &lt;/consumers&gt; &lt;/serviceProvider&gt; &lt;/serviceProviders&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` Now when the pact verify task is run, will look for methods annotated with `@PactVerifyProvider` in the test classpath that have a matching description to what is in the pact file. ```groovy class ConfirmationKafkaMessageBuilderTest { @PactVerifyProvider(&apos;an order confirmation message&apos;) String verifyMessageForOrder() { Order order = new Order() order.setId(10000004) order.setExchange(&apos;ASX&apos;) order.setSecurityCode(&apos;CBA&apos;) order.setPrice(BigDecimal.TEN) order.setUnits(15) order.setGst(new BigDecimal(&apos;15.0&apos;)) odrer.setFees(BigDecimal.TEN) def message = new ConfirmationKafkaMessageBuilder() .withOrder(order) .build() JsonOutput.toJson(message) } } ``` It will then validate that the returned contents matches the contents for the message in the pact file. ## Changing the class path that is scanned By default, the test classpath is scanned for annotated methods. You can override this by setting the `classpathElements` property: ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.11&lt;/version&gt; &lt;configuration&gt; &lt;serviceProviders&gt; &lt;serviceProvider&gt; &lt;name&gt;messageProvider&lt;/name&gt; &lt;verificationType&gt;ANNOTATED_METHOD&lt;/verificationType&gt; &lt;consumers&gt; &lt;consumer&gt; &lt;name&gt;consumer1&lt;/name&gt; &lt;pactFile&gt;path/to/messageprovider-consumer1-pact.json&lt;/pactFile&gt; &lt;/consumer&gt; &lt;/consumers&gt; &lt;/serviceProvider&gt; &lt;/serviceProviders&gt; &lt;classpathElements&gt; &lt;classpathElement&gt; build/classes/test &lt;/classpathElement&gt; &lt;/classpathElements&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` # Publishing pact files to a pact broker The pact maven plugin provides a `publish` mojo that can publish all pact files in a directory to a pact broker. To use it, you need to add a publish configuration to the POM that defines the directory where the pact files are and the URL to the pact broker. For example: ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.11&lt;/version&gt; &lt;configuration&gt; &lt;pactDirectory&gt;path/to/pact/files&lt;/pactDirectory&gt; &lt;!-- Defaults to ${project.build.directory}/pacts --&gt; &lt;pactBrokerUrl&gt;http://pactbroker:1234&lt;/pactBrokerUrl&gt; &lt;projectVersion&gt;1.0.100&lt;/projectVersion&gt; &lt;!-- Defaults to ${project.version} --&gt; &lt;trimSnapshot&gt;true&lt;/trimSnapshot&gt; &lt;!-- Defaults to false --&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` You can now execute `mvn pact:publish` to publish the pact files. _NOTE:_ The pact broker requires a version for all published pacts. The `publish` task will use the version of the project by default, but can be overwritten with the `projectVersion` property. Make sure you have set one otherwise the broker will reject the pact files. _NOTE_: By default, the pact broker has issues parsing `SNAPSHOT` versions. You can configure the publisher to automatically remove `-SNAPSHOT` from your version number by setting `trimSnapshot` to true. This setting does not modify non-snapshot versions. You can set any tags that the pacts should be published with by setting the `tags` list property (version 3.5.12+). A common use of this is setting the tag to the current source control branch. This supports using pact with feature branches. ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.12&lt;/version&gt; &lt;configuration&gt; &lt;pactDirectory&gt;path/to/pact/files&lt;/pactDirectory&gt; &lt;!-- Defaults to ${project.build.directory}/pacts --&gt; &lt;pactBrokerUrl&gt;http://pactbroker:1234&lt;/pactBrokerUrl&gt; &lt;projectVersion&gt;1.0.100&lt;/projectVersion&gt; &lt;!-- Defaults to ${project.version} --&gt; &lt;tags&gt; &lt;tag&gt;feature/feature_name&lt;/tag&gt; &lt;/tags&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` ## Publishing to an authenticated pact broker For an authenticated pact broker, you can pass in the credentials with the `pactBrokerUsername` and `pactBrokerPassword` properties. Currently it only supports basic authentication. For example: ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.11&lt;/version&gt; &lt;configuration&gt; &lt;pactBrokerUrl&gt;http://pactbroker:1234&lt;/pactBrokerUrl&gt; &lt;pactBrokerUsername&gt;USERNAME&lt;/pactBrokerUsername&gt; &lt;pactBrokerPassword&gt;PASSWORD&lt;/pactBrokerPassword&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` #### Using the Maven servers configuration [version 3.5.6+] From version 3.5.6, you can use the servers setup in the Maven settings. To do this, setup a server as per the [Maven Server Settings](https://maven.apache.org/settings.html#Servers). Then set the server ID in the pact broker configuration in your POM. ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.11&lt;/artifactId&gt; &lt;version&gt;3.5.19&lt;/version&gt; &lt;configuration&gt; &lt;pactBrokerUrl&gt;http://pactbroker:1234&lt;/pactBrokerUrl&gt; &lt;pactBrokerServerId&gt;test-pact-broker&lt;/pactBrokerServerId&gt; &lt;!-- This must match the server id in the maven settings --&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` ## Excluding pacts from being published [version 3.5.19+] You can exclude some of the pact files from being published by providing a list of regular expressions that match against the base names of the pact files. For example: ```groovy pact { publish { pactBrokerUrl = &apos;https://mypactbroker.com&apos; excludes = [ &apos;.*\\-\\d+$&apos; ] // exclude all pact files that end with a dash followed by a number in the name } } ``` ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.19&lt;/version&gt; &lt;configuration&gt; &lt;pactBrokerUrl&gt;http://pactbroker:1234&lt;/pactBrokerUrl&gt; &lt;excludes&gt; &lt;exclude&gt;.*\\-\\d+$&lt;/exclude&gt; &lt;!-- exclude pact files where the name ends in a dash followed by a number --&gt; &lt;/excludes&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` # Publishing verification results to a Pact Broker [version 3.5.4+] For pacts that are loaded from a Pact Broker, the results of running the verification can be published back to the broker against the URL for the pact. You will be able to then see the result on the Pact Broker home screen. To turn on the verification publishing, set the system property `pact.verifier.publishResults` to `true` in the pact maven plugin, not surefire, configuration. # Enabling other verification reports [version 3.5.20+] By default the verification report is written to the console. You can also enable a JSON or Markdown report by setting the `reports` configuration list. ```xml &lt;plugin&gt; &lt;groupId&gt;au.com.dius&lt;/groupId&gt; &lt;artifactId&gt;pact-jvm-provider-maven_2.12&lt;/artifactId&gt; &lt;version&gt;3.5.20&lt;/version&gt; &lt;configuration&gt; &lt;reports&gt; &lt;report&gt;console&lt;/report&gt; &lt;report&gt;json&lt;/report&gt; &lt;report&gt;markdown&lt;/report&gt; &lt;/reports&gt; &lt;/configuration&gt; &lt;/plugin&gt; ``` These reports will be written to `target/reports/pact`.
