HV-907 Fixing unwanted generated classes after build

> These two model classes are the only ones that actually compile. The others have some annotations errors that prevent them from compiling, so we don't see their .class files. Note that FieldLevelValidationUsingBuiltInConstraints has errors, but it's compiled with Kind.WARNING in #testThatProcessorOptionsAreEvaluated.

Ahh, good catch. That indeed explains things. I guess the -d option approach just does not work anymore.

> My best guess is if we specify a location in the fileManager, then it will take priority over the -d option.

Right. I think that is the way to go. I have no problem with that. I just was confused why we only saw one class compiled, but you explained this well now.
