Martin Franklin commented on MCOMPILER-157:
-------------------------------------------
I managed to get this working using the helper plugin in combination with a
second invocation of the compiler.
Let compiler run normally and generate the annotation processor output.
Then invoke the help plugin at the process-classes lifecycle stage, followed by
the compiler again.
Note that the order is important, so that the build-helper gets invoked before
the compiler.

> Maven Compiler Plugin by relying on javac by default, on Java 6 platform
> includes annotation processors in it's processing, these in end could
> generate sources that are placed by default in
> target/generated-sources/annotations. The later should be added to
> compileSourceRoots so that next plugin in execution would consider those
> sources.
> Please, see the attached test case and consider the attached patch in the
> next release of maven-compiler-plugin.
> thanks,
