Maven + Eclipse + RequestFactory validation tool: Duplicate class error

Hello all,

I migrated to GWT 2.4.0 and one of the first errors I got concerned the RequestFactory validation tool that needed to be run before launching the server. As I'm using Maven, I followed the instructions available here: http://code.google.com/p/google-web-toolkit/wiki/RequestFactoryInterfaceValidation#Maven_builds

I added the 2 plugins configurations. Didn't add the specific for Indingo as I'm using Eclipse 3.6.

That worked fine... in Eclispe.

Whenever I try to compile my project with maven through the command line, I get this:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project WEB-MODULE: Compilation failure: Compilation failure:

[ERROR] /workspace/PROJECT-ROOT/WEB-MODULE/target/generated-sources/annotations/PACKAGE_PATH/MY_REQUEST_FACTORYDeobfuscatorBuilder.java:[7,13] duplicate class: PACKAGE_PATH.MY_REQUEST_FACTORYDeobfuscatorBuilder

[ERROR] /workspace/PROJECT-ROOT/WEB-MODULE/target/generated-sources/annotations/PACKAGE_PATH/MY_REQUEST_FACTORYDeobfuscatorBuilder.java:[7,13] duplicate class: PACKAGE_PATH.MY_REQUEST_FACTORYDeobfuscatorBuilder

(I've substituted my project paths and names for the uppercase expressions above)

I've noted that this generated class is both under generated-sources/annotations and generated-sources/apt.

If I remove the plugins configuration, then I can compile with maven on the command line. But launching and using the application through Eclipse isn't possible without those plugins...

Anyone at least understand what's going on? Why this class is being generated twice and how to prevent if from happening while still launching the RF validation tool?

Thank you a lot for any help,
