title: Eclipse: add javadoc
body: <p>How can I generally add javadoc in eclipse for different packages.</p>
  
  <p>As an example:<br>
  I want to add all the javadoc for hibernate in eclipse, but I don't know how.
  I've read this article <a href="https://stackoverflow.com/questions/3815619/how-to-add-hibernate-javadocs-in-eclipse">How to add hibernate javadocs in Eclipse?</a> but I don't want to get hibernate tools because I already use STS and I don't understand the other comment.</p>
  
  <p>I'm using eclipse on Ubuntu.</p>
