title: Can I back out changes to my existing eclipse source code from a prior jar file.
body: <p>The jar was created in eclipse but does not contain source code, only class files.   Essentially I am wondering if Eclipse has a built in decompile feature that I can use to restore source code to an earlier version. </p>
  
  <p>If I need to use a 3rd party decompile tool what is recommended?</p>
  
  <p>Going forward, I will be sure to include source files in the .jar
  Thanks in advance for any advice.</p>
  
  <p>I am using eclipse 
  Eclipse Java EE IDE for Web Developers.
