My project has more than one vcs roots within one SVN repository in order not to get a lot of unused sources:
1. dir1\dir2\dir3, local checkout path = dir2
2. dir1\dir4\dir5, local checkout path = dir4
under dir3 structure is following:
after checkout in work directory of build agent I see following structure:
subdir1 (all subdirs empty)
subdir2 (all subdirs empty)
subdir3 (all subdirs empty)
subdir4 (all subdirs empty)
Subdir1-4 in root of work directory are wrong.
Don't ask why, but that structure messes up my build process (which is unusual, for sure). I resolved problem by having only one vcs root and downloading all the sources. Problem appeared when I updated TC to build 1574 from 1492. Usual checkout doesn't give such results, of course.
