Since the promotion of book and maven-plugin I can't build the doxia dev
site anymore. I am seeing exactly the problem described at MNG-3167 (in
short: If your project contains a Maven plugin, then it is impossible
to build aggregated Javadoc). It works if I set aggregate=false and if I
remove the maven-plugin. Below is the full stacktrace of 'mvn site', I
am using maven-plugin-plugin-2.3, maven-javadoc-plugin-2.3 and maven
2.0.6. Any idea?
Thanks,
-Lukas
