The tool checks Camunda projects for consistency and discovers errors in process-driven applications.
Called as a Maven plugin or JUnit test, it discovers esp. inconsistencies of a given BPMN model in the classpath and the
sourcecode of an underlying java project, such as a delegate reference to a non-existing java class or a non-existing Spring bean.
