title: Jenkins Fail with: Host key verification failed
body: <p>I downloaded and installed Jenkins for Mac OSX on my Macbook Pro (OS: Mountain Lion). I now want to set it up to pull down a project from bitbucket and do an automatic build.</p>
  
  <p>I created the ssh key, added it to bitbucket and tried to setup a build job. However, I get the error:</p>
  
  <p>Failed to connect to repository : Command "git ls-remote -h  HEAD" returned status code 128:
  stdout: 
  stderr: Host key verification failed. 
  fatal: The remote end hung up unexpectedly</p>
  
  <p>I tried to remove the domain causing the problem from known_hosts but am still getting this error.</p>
  
  <p>Please advise.</p>
