title: Where does Jenkins store Downstream Projects information in the file system?
body: <p>i have two questions.</p>
  
  <ol>
  <li><p>why Jenkins automatically picks up the downstream projects? how to stop jenkins automatically picking up downstream projects? </p></li>
  <li><p>where does jenkins stores (in the file system) the downstream &amp; upstream project of any project? if I know this I can probably go and edit the necessary configuration according to my need?</p></li>
  </ol>
  
  <p>note: the projects mentioned above are maven projects which build java code</p>
