title: How to build scene builder from openjfx sources
body: <p>I'm trying to build JFX scene builder from openjfx sources but I'm can't find a valid howto or clear documentation, I've already read the official openjfx instruction that are not for scene builder but for the whole sdk, so I've installed mercurial and gradle but i have some question:</p>
  
  <p>1) Can i build only the scene builder without building the whole SDK ?</p>
  
  <p>2) I've tried to run gradle from apps/scenebuilder folder it run successfully but where to find the generated artifact ? I was expecting a target folder with a jar inside but nothing was generated.</p>
  
  <p>3) I've googled around and found that it should be possible to download only the scene builder sources from mercurial but i can't find any valid mercurial repo.</p>
  
  <p>any help will be highly appreciated, many thanks.</p>
