Jenkins version: 1.476
Plugin version: 2.30
My Maven build creates a cpd.xml that looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<pmd-cpd>
</pmd-cpd>
And I'm seeing the following exception in the Jenkins log when the DRY plugin is enabled:
org.apache.commons.digester3.Digester error
SEVERE: Parse Error at line 2 column 10: Document root element "pmd-cpd", must match DOCTYPE root "null".
org.xml.sax.SAXParseException: Document root element "pmd-cpd", must match DOCTYPE root "null".

Do I need to somehow disable validation on the cpd.xml file? Or is the cpd.xml file malformed?
The exception seems to occur regardless of whether the cpd.xml file contains warnings or not.
Despite this exception, the plugin appears to report the correct number of duplicate code warnings.
However, the exceptions are filling the Jenkins log.
