title: How can I delete files in directory using jenkins
body: <p>In my system, I am downloading new build everyday in 1 folder and then use it for further causes but after running jenkins job I want to delete files in the folder (not workspace) which will delete specific folders from same directory. This will help me downloading new build every time based on different jenkins job running on same machine.</p>
  
  <p>EG:</p>
  
  <p>I am downloading x.x build and then running jenkins job on machine and then if I want to run other job which requires x.y build, it will just see if SOME build is already there in folder. if it is there, it will not download any kit after that. So, now simplest thing I can do is delete x.x after every jenkins run (post build ) so it will download x.y next time.. </p>
  
  <p>Please help.
  Thanks in advance</p>
