I have several Maven2 jobs that run on a schedule and on occasion, randomly, one or more of those jobs will fail because the workspace is mysteriously empty. I will have to go into the Perforce configuration and force the workspace to be synced and run the build again and it'll be fine for a day or two. The Perforce plugin flag to clear the workspace is NOT set, and the flag to force a sync is also not automatically enabled (when I check after a failed build) - so it seems that maybe it's not the plugin clearing the workspace. I also can't tell when it's cleared, whether it's before or after a build, but for whatever reason the build thinks everything is kosher then fails because it can't find the POM. This began happening some time ago after upgrading 1.372, but never happened on the prior version (1.342 I think).
