I\'ve installed os x server (Mavericks) on my mac and would like to add bot. For some reasons my remote repo is located on other external server and I have access to it by usern
I experienced a similar issue with scheme action build scripts when attempting to run git commands against a github repo protected by ssh key pairs.
Bots run builds using a _teamsserver system account. As you've discovered, these accounts don't have home directories by default. To setup builds to access and modify their home directory, I had success with the following (your mileage may vary):
sudo mkdir /var/teamsserver
sudo chown -R _teamsserver:_teamsserver /var/teamsserver/
sudo chmod -R 770 /var/teamsserver/
HTH
