I have two working copies of a Subversion repository, one of the trunk, and one of a branch I created.
I accidentally deleted the branch in a repository browser. How
I ran into this problem, but the above command didn't work for me. What did was much easier. I checked out the branch at one revision before I removed it.
The revision that was removed was 9331. I checked it out at 9330:
svn co https://svn.acme.com/svn/giantFlySwatterTargetingSystem/branches/bug1234@9330 restored
That was the easy solution I wanted.
