title: Copy files from remote Jenkins workspace
body: <p>Im trying to create a cross-compilation job, that will build my code for both Windows &amp; Linux.
  I have set up Windows &amp; Linux jenkins nodes, and configured two jobs, one with 'windows' label to run on my Windows machine and the other with 'linux' label to run on my linux machine.
  I installed MultiJob plugin, and wrapped both jobs to run in parallel
  When both finishes successfully, I want to copy all the generated files and do operations on them
  In other words I want to copy the files from both jobs remote workspaces for further operations
  Can anyone suggest a way how to do it?</p>
