title: Trying to run decompiler in Eclipse Luna
body: <p>I am trying to debug a jar file I don't have source for, in Eclipse Luna</p>
  
  <p>I have tried various decompilers, and can't get things to run.</p>
  
  <p>The most recent seems to be JDEclipse-Realign at <a href="http://mchr3k.github.io/jdeclipse-realign/" rel="nofollow noreferrer">http://mchr3k.github.io/jdeclipse-realign/</a></p>
  
  <p>It installs without any trouble. I have set set the default file association for "class without source" to be "Class File Editor" like this</p>

  <p>I added the jar file to be debugged as an external jar to my project.  And when I expand that and right click on a .class file I get what is shown on the web page for JDEclipse-Realign, with Decompiled Source as the default.</p>

  <p>And I am getting the blue and white icons for JDEclipse-Realign when I select a class file.</p>

  <p>But no decompiled source :(  And clicking the blue icon for Attach Decompiled Source does nothing.</p>
  
  <p>I feel like I must be missing one basic thing, but can't figure it out.  No errors, just no source.</p>
  
  <p>Or should I be using a different decompiler?
  Are any known to work in Luna?</p>
