I have had lots of great success with this plugin . . . thank you so much.

I have a Jenkins instance where the option "Build Record Root Directory" has been set (Jenkins->Config->Advanced right under Jenkins Root).

So JENKINS_HOME is under C:\Program Files, but the build records are under C:\jenkins . . . see error messages below.

In this case, the plugin is throwing the following error for all jobs:

ERROR: Publisher org.jvnet.hudson.plugins.groovypostbuild.GroovyPostbuildRecorder aborted due to exception
java.lang.IllegalArgumentException: Err ! File [C:\jenkins\fmerrow3\Update Robo CSPECs\builds\2013-10-10_14-06-37\build.xml] seems not to reside in [C:\Program Files (x86)\Jenkins] !
