Jenkins CI on Windows - Git can't access remote submodules - even public ones.

I'm setting up Jenkins on a windows machines, looks great. But after setting up all the credentials, projects with Git submodules cause a problem - we get git authentication errors.

These errors go away if you set the environment variable HOME to the parent of your .ssh directory. There's also a JENKINS_HOME variable. Possibly setting this and copying the .ssh directory to Program Files (x86)/Jenkins might have the same effect, but I've not tested that yet.
