Thomas Broyer commented on MCOMPILER-122:
-----------------------------------------
This is a bad idea IMO.
First, annotation processors shouldn't depend on non-java inputs, because
JSR-269 doesn't allow you to track dependencies of generated
sources/classes/resources to anything else than "elements":
http://docs.oracle.com/javase/7/docs/api/javax/annotation/processing/Filer.html
(File#getResource is rather meant to read resources that were previously
generated by File#createResource, but should still be used with care).
Also, including target/classes to sourcepath could lead to classes being
compiled or recompiled when they shouldn't (when you have *.java files as
resources but not sources). Fortunately, there'd be an easy workaround here:
exclude *.java files from project.build.resources and use
resources:copy-resources after the compile phase to copy the *.java files;
that'd still be a hack if you ask me.

> Project: Maven Compiler Plugin
> Issue Type: Bug
> Affects Versions: 2.1
> Reporter: Milos Kleint
>
> annotation processors which load non-Java resources from the sourcepath, will
> currently get only the src/main/java folder.
> Unfortunately just adding src/main/resources to -sourcepath does not suffice,
> due to a bug in javac:
