Is there an open source project that can serve as a good example on how to use the maven site plugin to generate reports? I would prefer it to

• consist of many modules, possibly hierarchically structured
• use as many plugins as possible (surefire, jxr, pmd, findbugs, javadoc, checkstyle, you name it)
• the reports should be aggregated: if some tests fail you want to have a single page that shows all modules with failing tests, not only a gazillion individual pages to check
• include enterprisey stuff (WAR, EAR etc), but this is not so important.

The idea is to have something where you can gather ideas on how it is done and what is possible.
