title: Hudson: Multiple Jobs on same repository
body: <p>It looks like <a href="https://stackoverflow.com/questions/2716250/how-can-i-setup-hudson-to-use-the-same-repository-for-different-projects-and-mai">How can I setup Hudson to use the same repository for different projects and maintain separate change logs?</a> but is not.</p>
  
  <p>In my case the scenario is a little bit different:</p>
  
  <p>Trunk</p>
  
  <p>-----Project 1</p>
  
  <p>-----Project 2</p>
  
  <p>-----Project 3</p>
  
  <p>-----Common Libraries</p>
  
  <p>Common Libraries contains shared libraries among the projects. Right now I'm setting each project a separate job for the same reasons: independent reporting (java doc, test results, etc)</p>
  
  <p>Is there a way to prevent each job have their own cop of the repository (checked out from SCM)?</p>
  
  <p>I guess I can zip the repository and extract in the next project but I hope there's something else in place. I doubt this is an unique setup.</p>
