MAESTRO-3033 If existing URL doesn't match incoming one, will fail
Error similar to:

Request for git clone of '/tmp/../tmp/maestro-git-repo' into '/tmp/maestro-git-wc', but /tmp/maestro-git-repo already squatting the directory.
This usually indicates two compositions are set to use the same directory for their checkouts.
Either manually remove '/tmp/maestro-git-wc' or select the 'Clean Working Copy' option (if left on this will slow down repeated builds, increase checkout/update time, and generally reduce system efficiency)
