/**
* A command line application to create a new, empty service. This *does not* add the new service to the shared pom.xmls, that
* should be done via {@link FinalizeNewServiceModuleMain}.
*
* Example usage:
*
* mvn exec:java -pl :release-scripts \
* -Dexec.mainClass="software.amazon.awssdk.release.CreateNewServiceModuleMain" \
* -Dexec.args="--maven-project-root /path/to/root
* --maven-project-version 2.1.4-SNAPSHOT
* --service-id 'Service Id'
* --service-module-name service-module-name
* --service-protocol json"
*
*
* By default the service new pom will include a dependency to the http-auth-aws module, this is only needed if the service
* has one or more operations signed by any of the aws algorithms, e.g., sigv4 or sigv4a, but not needed if the service uses,
* say, bearer auth (e.g., codecatalyst at the moment). Excluding this can be done by adding the
* {@code --exclude-internal-dependency http-auth-aws} switch. For example
*
* mvn exec:java -pl :release-scripts \
* -Dexec.mainClass="software.amazon.awssdk.release.CreateNewServiceModuleMain" \
* -Dexec.args="--maven-project-root /path/to/root
* --maven-project-version 2.1.4-SNAPSHOT
* --service-id 'Service Id'
* --service-module-name service-module-name
* --service-protocol json
* --exclude-internal-dependency http-auth-aws"
*
