Copy artifacts sometimes fails to copy Mercial lock file

[davehunt]

Occaisionally the copy artifacts fails to copy the Mercurial repository due to the lock file not being present.

I suspect the file is removed between listing the files and copying them. We should see if there's a way to exclude lock files when copying artifacts.

This could happen with any file of the get_mozmill-tests or get_mozmill-automation job. I think the problem here is that we tell copy artifact to take the last finished build from the workspace. It might help if we change that to the last successful build. Keep in mind that we do not clear the workspace for those jobs.

For the get_mozmill-tests job we might haven't to do a change as of now, given my pull #260, where I change it from copy artifact to the Clone Workspace plugin.

Oh, fyi we are seeing this more often now given that the get_mozmill-tests job gets run each 5 minutes now.

This should have been fixed now with the upgrade of Jenkins in #260.
