Description:

When configured as post-build action, both plugins attempt to parse XML documents using a third party xml parser (xerces) on the slave node. As this library is not part of most JDK's it is usually not installed on the slave nodes. This then fails with the cryptic stacktrace:
[PMD] Collecting PMD analysis files...

Downloading the xerces library manually and adding it to the classpath works on linux, but fails on windows. In that case Jenkins outputs the following message to stdout:
<===[JENKINS REMOTING CAPACITY]===>rO0ABXNyABpodWRzb24ucmVtb3RpbmcuQ2FwYWJpbGl0eQAAAAAAAAABAgABSgAEbWFza3hwAAAAAAAAAAY=
I would expect that:
- complicated operations, such as parsing an xml file, are performed solely on the master node;
- a slave node does never need any third party libraries;
- plugins are not allowed to execute part of their code on the slave nodes.
