title: Jenkins; Inject Environment Variable in Jelly field?
body: <p>This has been bugging me for a little while, there is a list with environment variables and I want to use them in the configuration of one of my builds on my own custom plugin, as such:</p>
  
  <p><img src="https://i.stack.imgur.com/vLbNv.png" alt="enter image description here"></p>
  
  <p>So in this case I would like the <code>${WORKSPACE}</code> to resolve to a path that has been configured by the environment. </p>
  
  <p>Anyone know how to do this? I can't seem to find it as a Jelly tag.</p>
