title: configure git repository in jenkins
body: <p>I'm trying to configure the repository:
  <a href="https://github.com/javpaw/game-of-life" rel="nofollow noreferrer">https://github.com/javpaw/game-of-life</a></p>
  
  <p>into a job in jenkins using git plugin, but when I put the address of the repository:
  git@github.com:javpaw/game-of-life.git</p>
  
  <p>Source Code Management -> git -> repository Url I got this error:</p>
  
  <blockquote>
    <p>Failed to connect to repository : Command "/usr/bin/git ls-remote -h
    git@github.com:javpaw/game-of-life.git HEAD" returned status code 128:
    stdout: stderr: No protocol specified No protocol specified</p>
    
    <p>(ssh-askpass:18881): Gtk-WARNING **: cannot open display: :0.0 Host

  <p>I found this question here in github: <a href="https://stackoverflow.com/questions/12490981/why-git-fail-to-connect-to-local-repository-with-jenkins-bad-config-file">Why Git fail to connect to local repository with Jenkins (bad config file)?</a></p>
  
  <p>but was not useful because I'm using Ubuntu 12.04</p>
  
  <p>How can I solve this issue?</p>
  
  <p>thanks.</p>
