I'm using version 1.2.3 of jdepend.

I am generating output with pdepend as per the instructions listed on http://agile.dzone.com/news/continuous-integration-php

I have clicked the post-build action box for jdepend, and listed the absolute path to my file. However, my build output lists

[JDepend] JDepend plugin is ready
[JDepend] Couldn't generate JDepend file at '/var/lib/jenkins/workspaces/test-job/build/reports/jdepend.xml'java.lang.NullPointerException
