I generate more than one javadoc in my build projects.
So I currently can not use the included javadoc feature, since it only allows
exacltly one javadoc location per project.

What I have is:
workspace/javadoc/model/<javadoc of model>
workspace/javadoc/service/<javadoc of service>

If I specify in the config for javadoc: workspace/javadoc it will give me an
error after the build has run. I am not allowed to specify wildcards.
