Pretty much *all* build systems have this problem.

It's common behavior to all build systems, particularly Java-esque ones that track dependencies through the .class files in the "-d" target directory of javac.

In the face of refactoring and certain strange scenarios, .class files remain in the target directory for which either the source files have a changed transitive dependency or the source no longer exists or a constant is not deemed worthy of a recompile or what-all.

Later another class sees something in the now-no-longer-valid .class file and weirdness ensues.  Finally the hapless programmer does a full "clean", and voilà! Problem solved.
