Hi, we've been using Jenkins for a few months now, and recently one of
our projects which haven't had any code changes in months have
started failing... wanted to forward the issue here to see if there
was a solution or workaround to the problem.

no change for http://<svn-server>:8080/applauncher/trunk since the
previous build
