I took a maven2 Java project and loaded it into Hudson using the maven2 type.
It built fine. The project showed a project with a single module, that module
being the whole of my project. The pom file was configured to have the java
compiler spit out warnings and deprecation notices.

I installed the warnings plugin, checked the warnings box in the project
configuration page, and kicked off another build.

The warnings plugin almost immediately reported 0 warnings, despite many
warnings appearing in the module's log. It seems like it checks only the log of
the parent project and not the module underneath. I believe that this is either
a bug or a fundamental misunderstanding on my part of how to properly use this
plugin. If it's the latter, I apologize for wasting your time, but do you have
any idea what I'm doing wrong?
