I can't seem to get the tagging for subversion to work. To test the config I have been testing with the 'Label this build sources' link on the Changes report for a successful build. No matter what I put into the 'Labeling rules' 'trunk' gets prepended to my config for both the left and right of the =>. So if I have 'trunk=>tags' in the 'Labeling rules' I get the following error, notice how 'trunk' is prepended.
Failed: Failed to set label 'build-184.108.40.2066': Labeling the path 'trunk/trunk' to 'trunk/tags/build-220.127.116.116' has failed with the error: svn: Path trunk does not exist in revision 61
