I found my problem. As expected, it was a simple one. The constructor
for PreBuildCleanup requires two arguments; the list of patterns and a
boolean determining whether or not to apply the patterns to directories.
Somehow I must have been looking at an old version of the javadoc for
hudson.plug
I've been working on a Groovy script to add PreBuildCleanup to certain
jobs. I followed the example of the Groovy script to add timestamper to
all jobs [1]. The problem is, I can't come up with the right constructor
for the PreBuildCleanup. I know it must be simple, but I'm just learning
to pok
