Getting JavaDoc warnings from Maven

I have a project that uses Maven 2 to build both manually and through 
CruiseControl.  I have been able to get jUnit, CheckStyle, and PMD 
reports merged into the project log file, but the JavaDoc warnings don't 
seem to be recognized by CC, at least as far as the coding violations 
graph is concerned.  Is there a property that I have to set on the Maven 
JavaDoc plugin to get it to generate a report of warnings?  How can I 
make this work?

Thanks,
Chris Lieb
