public class CommentHasStringValueProcessor
extends AbstractProcessor

I think I figured out how to use annotation processors in maven. It's more or less automatic and you don't even need to tell maven, with one minor exception. The idea is to create a project for the annotation and another for the annotation processor. Then, a project that uses the annotation can simply set up the dependency on the other projects. You have to turn off processing, -proc:none on the processor project itself but other than that, java 6+ more or less tries to apply any processors it finds during compilation. maven just works. Also you need a META-INF/services/javax.annotation.processing.Processor file with "org.antlr.v4.test.runtime.CommentHasStringValueProcessor" in it.
