Stop buildout if a git error happens

[idgserpro]

I would like to stop buildout when mr.developer hangs. For example, when a error happens in the git side:

mr.developer: git cloning of 'my.package' failed.
mr.developer: ssh_exchange_identification: Connection closed by remote host
mr.developer: fatal: Could not read from remote repository.
mr.developer: 
mr.developer: Please make sure you have the correct access rights
mr.developer: and the repository exists.

Is this possible somehow, with a new parameter like stop-on-error from https://github.com/collective/plone.recipe.command?
