title: Dynamically Fill Jenkins Choice Parameter With Git Branches In a Specified Repo
body: <p>I have a parameterized Jenkins job which requires the input of a specific Git branch in a specific Git repo.  Currently this parameter is a string parameter.</p>
  
  <p>Is there any way to make this parameter a choice parameter and dynamically fill the drop down list with the Git branches?  I don't want to require someone to maintain this choice parameter by manually configuring the drop down every time a new branch is created.</p>
