I'm trying to parse results of PMD execution with PMD plugin but I'm getting this error:

org.xml.sax.SAXException: Input stream is not a PMD file.

Command line execution from within a Execute Shell code block for PMD version 5.2.3 is: /opt/pmd-bin-5.2.3/bin/run.sh cpd --minimum-tokens 100 --files files-dir --language cpp --format xml --encoding UTF8 > pmd.xml

Command line execution from within a Execute Shell code block for PMD version 4.2.6 is: java -cp /opt/pmd-bin-4.2.6/lib/asm-3.2.jar:/opt/pmd-bin-4.2.6/lib/jaxen-1.1.1.jar:/opt/pmd-bin-4.2.6/lib/junit-4.4.jar:/opt/pmd-bin-4.2.6/lib/pmd-4.2.6.jar net.sourceforge.pmd.cpd.CPD --minimum-tokens 100 --files segmenter/ --language cpp --format xml > pmd.xml

Please find attached the pmd.xml output file.

I'm not sure if this is a bug or I'm doying something wrong, but I cannot find a solution to this problem.
