if you're using a bat file, you ran into the 8192 char size limit.
Write your paths into a text file, separated by newlines and then pass
the path to that file (and of course leave the /notempfile param).

Actually the problem was not related to size limitations.
I wasn't aware of the fact that all directories specified in the "/
path:" parameter must be subdirectories of a common working copy
