I have jenkins installed on a Ubuntu machine. I have a git repo hosted on a different Ubuntu server that I usually access via ssh. I created a new build project and I am just trying to get the git fetch working. I defined the URL correctly and created a new set of credentials that are a username and password. I am getting the error in the attached file. I don't know how else to debug this problem. I ran the following command in a terminal on my jenkins server (running as the jenkins user) and it prompted me for my password. When I entered the password, it printed nothing to the standard out or standard error.

git -c core.askpass=true ls-remote -h mobius-test@blue.perform.illinois.edu:/srv/git/grp/mobius/Mobius.git HEAD
