title: How to identify projects using a specific JDK installation in Jenkins
body: <p>I would like to clean up the list of JDKs managed by our Jenkins CI server.</p>
  
  <p>For instance there are several versions of JDK 8 whereas I'd like to only have one of them (the latest). So I am looking for a simple way for identifying all those Jenkins jobs explicitly using one of the other JDK installations so I can change them to use the one remaining JDK install.</p>
  
  <p>Is there a better way to do so apart from manually clicking through all jobs and examine which JDK they use?</p>
