> According to http://maven.apache.org/plugins/maven-pmd-plugin/pmd-mojo.html, 
> the excludeRoots property is supposed to suppress PMD report generation for 
> certain source roots. However, in practice this does not work with this type 
> of configuration:
>                               <configuration>
>                                       <excludeRoots>
>                                               
> <excludeRoot>target/generated-sources/axis</excludeRoot>
>                                       </excludeRoots>
>                               </configuration>
> On line 265 of AbstractPmdReport, a new File object is created for each 
> excludeRoot element. Then, on line 346, each compileSourceRoot is checked to 
> see if the List of excludeRoot File objects contains it. This test will never 
> return true as the compileSourceRoot File objects are absolute and the 
> excludeRoot File objects are relative.
> The simplest solution (seen in the attached patch) is to create absolute File 
> objects for each excludeRoot.
> I tried created a unit test to demonstrate this problem, but couldn't quite 
> nail it down. I'll keep trying....
