A developer had a branch, which I'll call 'SPC' for the purpose of this ticket. It exists at branches/SPC at revisions r1697, r1709, and r1710. For r1708, the developer who 'owns' the branch decided to delete it. There is a commit message, but r1708 no longer contains branches/SPC.
Bamboo insists on trying to build r1708 and this always fails because there's nothing to check out.
I'd like to be able to move Bamboo forward to use at least r1709. How can I do that?
