Usually the only time I see things like this is if I do an svn update and then a mvn install without cleaning. I'm guessing some of the classes that should be recompiled are not, and a clean usually fixes it. Maybe there is a bug in the compiler plugin that does not correctly determine out of date classes. In your case, maybe one of the tests was removed or renamed? And now surefire can't find something it's looking for? That's all I can think of that could cause an error like that.
