This is with Hudson 1.290, and version 2.4 of the Compiler Warnings plugin. The
problem was there with earlier versions on Hudson.

Looking at the summary page for a build, I see the message "During parsing of
the log file an error has been reported.". Following the link to the error
messsages shows a series of messages of this form:

"Module gda: Skipping file gda of module
/scratch/hudson_workspace_master/GDA_trunk_gda/uk.ac.diamond.gda.core/classes/test/gda/_init_.py
because it's empty."

However, I have configured the plugin to exclude these files.

Include pattern:
uk.ac.diamond.gda.core/*/.java,uk.ac.diamond.gda.core/*/.py
Exclude pattern:
uk.ac.diamond.gda.core/**/_init_.py

(these are relative to the workspace root, which is
/scratch/hudson_workspace_master/GDA_trunk_gda).

So, why is the plugin looking at the files? Doesn't the exclude list override
the include list?
