title: Free space in Jenkins deleting 'builds' directory
body: <p>I'm using Jenkins to execute daily tasks with my projects, but every execution, Jenkins stores a 20MB dir in <strong>PROJECT_HOME/builds</strong>, so after a lot of executions, the space in the disk of every project is huge (10GB for some Jenkins tasks).</p>
  
  <p>It isn't very important for me to store the result of the previous executions, so what I want to know is that if exists a way to say Jenkins no to store that information.</p>
  
  <p>Does anybody know how to avoid Jenkins to store result of old executions?</p>
