I just started with IntelliJ, so this might be a stupid question.
I want to run some unit tests but the previously performed compiling (or "Make"), shows errors: "cannot find symbol method foo()". But, this method exists. Other methods in this class work fine (no errors shown), even code completion is working for these methods. The strange thing was, that it worked before. After I have done some refactoring (in completely other parts of my app, I did not touch any class that is in the error list now) this weird behaviour occurs.
What could be my mistake here. Do I need to set some settings or to check something? Is there something like "Cleanup Project" like in Eclipse?
Thanks in advance,
