             Summary: Internal Error verifying doxia
                 Key: MNG-6860
                 URL: https://issues.apache.org/jira/browse/MNG-6860
             Project: Maven
          Issue Type: Bug
            Reporter: Elliotte Rusty Harold


Checked out doxia-site from [https://github.com/apache/maven-doxia-site] and ran mvn verify on a Mac with JDK 8.

 

I estimate there's three different errors here to make this happen. This issue is for whatever in core is causing an InternalErrorException when likely faced with a somehow broken project setup.
