title: Jenkins Workspace build and multiple Branch
body: <p>I currently take care of the establishment of an integration platform continues in my business.
  I have several(3) GIT branches for my solution.
  Today Jenkins detects Push on each of my branches and generates a compilation in
  C: \ Program Files ( x86) \ Jenkins \ jobs \ PROJECT \ workspace</p>
  
  <p>I wish a Workdir ( workspace ) different depending on the branch, is this possible ?
  Exemple : 
  C: \ Program Files ( x86) \ Jenkins \ jobs \ PROJECT \ workspace\BranchA
  C: \ Program Files ( x86) \ Jenkins \ jobs \ PROJECT \ workspace\BranchC
  C: \ Program Files ( x86) \ Jenkins \ jobs \ PROJECT \ workspace\BranchB</p>
