I have a bit of a problem getting code coverage reports for both Integration Tests and Unit Tests in Sonar for a Maven Plugin project (which uses invoker plugin for the integration tests).
I can't use the default Jacoco coverage tool for the unit tests, as these use Powermock, which results in 0% coverage for classes using that. On the other hand, I can't find a reliable way to get results for the Groovy-based integration tests without using Jacoco.
So what I need is for Cobertura to produce a Unit Test report, Jacoco to produce an Integration Test report, and for Sonar to be able to read the lot.
I tried using the example here https://github.com/Godin/sonar-experiments/tree/master/jacoco-examples/maven-invoker-plugin-example but eliminating the executions bound to the test phase, but I then get a unit test coverage of '-' in Sonar. I think the reason for this is that to get this method to work, I need to speicify Jacoco as the core coverage tool for Sonar.
Any ideas on a way round this? My pom.xml follows:
