Created attachment 281270 [details] video of the problem I have a code file that Eclipse will not run changes with. It only runs an old version of the code, and I don't even know where it is coming from. Reboots to the system do not clear it. Moving the files and retrying does not clear it. When eclipse starts, it asks for an update which gives the following exception.

These seem to be two different problems. About old code being run: is "Build Automatically" switched on? (In the global "Project" menu.) The update problem is something else; no idea about that.
(In reply to Thomas Wolf from comment #1) > The update problem is something else; no idea about that. The update problem is caused by Bug 558462.
In the video at second 4 you get a warning message about errors in required projects. Depending on the type of error Eclipse doesn't recompile dependant projects upon change, so if you added the "System.out.println" statement you are missing after the error in project Omega appeared, it's most likely caused by executing an "old" class file.
