It's certainly the case that this is used. However, "cannot be copied"
sounds like a permission problem, which there is not.

Just ask for it, and you'll be granted access.

I still fail to see the bug - it's by design that later build steps are
not executed if earlier build steps failed. It would be possible to let
the slaves start over with an entirely new checkout on every build, but
that would significantly increase bandwidth consumption, and delay
builds.

In any case, I won't have time to look into this in the near future.
