Maven2 and surefire plugin issues with TestNG test cases

I was facing problems executing my TestNG unit tests under Maven 2.0.4 with the maven-surefire-plugin 2.2. The tests were not started and I got the following result from the plugin:

I did not specify a testng.xml file because the surefire plugin docs say it is not necessary. And exactly that is the problem! If I provide a testng.xml file my unit tests are executed! Hm, so I digged a little bit further and found
the Issue http://jira.codehaus.org/browse/MSUREFIRE-117 in Jira.



I tried the fix and it solves the problem. Now my TestNG unit tests are executed even if I do not specify a testng.xml file.
Maybe this will help others. I hope the bug will be fixed very soon (I voted for it).
