title: How to run a Jenkins build only if another build has been successful?
body: <p>I want Jenkins to run a regularly scheduled build A <strong>only</strong> if another regularly scheduled build B has been successful. If the build A has failed the this way dependent build B should not run (since it would fail also). 
  I don't want to trigger B from A directly since B as a completely other schedule (runs more infrequently).</p>
