title: Annotation processor output in maven
body: <p>I'm using JSR 269 as a way to analyze code during compilation and to fail it if needed.
  I'm having troubles with displaying output of my annotation processor in maven (Ant does show the output)
  I'm using javax.annotation.processing.Messager to display warnings and errors, but in maven I don't see it's output. (I do know it runs though, because it generates code like it should).
  Any ideas?</p>
