title: Jenkins Global Pipleline Library - how to copy a directory from resources dir to workspace?
body: <p>Is there an environment variable that defines the global lib root so I can just shell out and cp a dir from the global pipeline library's resources dir? I don't want to read a single file, I want to copy an entire dir and it's files. </p>
  
  <p>Unfortunately it seems like this may not be possible - if not, how would you do this? </p>
