Git integration sometimes fails with github

[rb2k]

This happens from time to time:
Extra info: I run this from a non-interactive script (stdin isn't the terminal)

[INFO] Connecting to SCM

Are you sure you want to continue connecting?

Which OS are you running from: Unix-based or Windows?
In any case it's an SSH issue, Unlike HTTPS, there is no chain of certificate authorities that establish trust for SSH. So you have to tell your computer that you trust github.com the first time you connect over SSH.

If you're using Unix, simply run:

ssh git@github.com

This was running on OSX. I did manually connect before (and can do regular checkouts just fine), not quite sure what triggered this problem.
