I have several Eclipse Plugin-Projects which I want to compile using Maven & Tycho. The project can be found at github. There you see three projects with their pom.xml files. With that I aim to run unit test using JMockit.
To start Maven, I switch into the maven.parent directory and execute mvn clean verify which produces the following output:
D:\maven-test\maventest.parent>mvn clean verify

Exception in thread "Attach Listener"
So I conclude that -javaagent is somehow required. Confusing: When using eclipse to run the test it works like a charm!
The jmockit-1.20.0.jar which is passed to -javaagent and therefore is used to run the tests is exactly the same as the one in the eclipse repository. I also added @RunWith(JMockit.class) to the test. As described here, I used all three methods.
So do you have any clue what I can do?
I found a solution: If I execute the tests in Eclipse using Run As -> JUnit Test, all works fine. If I execute the tests using Run As -> JUnit Plugin Test, the same error occurs. Researching gives no result and the support by JMockit is cancelled ("won't fix").
Since the "normal" tests are working perfectly I'm able to use the "normale" maven-surefire-plugin instead of the tycho-surefire-plugin. The only difference is the test phase (test instead of integration-test) and that there is no OSGi environment (which I do not need). Solution in POM files is as follows.
