Git Sources - Clone issue when multiple sources use the same repo #460

If 2 or more sources use the same repo then there is an error thrown when cloning:

[Mosaic] Source Error: Command 'git clone <repo url> --no-checkout --origin=origin' failed: 128. fatal: destination path '<repo project-name>' already exists and is not an empty directory.

Basically, this is a timing issue at heart.

both sources start up
check for a previous clone which doesn't exist
clone the repo
find out that the other source has created the repo directory first
throw error

We have logic that checks for a previous clone but it does not work across sources. A git source is only aware of what it has done.

Workaround

Schedule the sources to start with different delays. Delayed sources won't attempt a clone and will re-use the earlier cloned repo.
