I have just started playing around with Git and would like to push a personal project to a newly created, private repo on Bitbucket using Aptana Studio 3. I tried to use the Git integration in Aptana but I couldn't figure out where to enter my username and password for Bitbucket anywhere. I tried using the Team > Share Project context menu but that keeps throwing the following message:

Warning: Permanently added the RSA host key for IP address '207.223.240.181' to the list of known hosts. Permission denied (publickey). fatal: The remote end hung up unexpectedly

I'm pretty sure that's because my repo is private. However, I couldn't find a provision to provide any form of credentials for linking to a private repo.

Any ideas?
