We have a Maven build which failed in an pre-build step and therefore even reach the mvn clean goal.
Because the previous, unstable build had failed tests, these tests were shown as belonging to the failed build - even thought the build didn't run any tests.

This sound like a general problem in the plugin, because it scans the workspace for TestNG result files, so when the workspace is not cleared the old test results are naturally considered to be part of the new build.
Maybe you still have an idea how this could be fixed

Thanks
