title: Add source files to my jar using Maven
body: <p>I wanted to know the right way I should act.
  I have a project which I have compiled into a jar file using maven plugins.</p>
  
  <p>Now, I need to add javadoc , source code , of my project and my tests.</p>
  
  <p>How should I do it?</p>
  
  <p>Basically maven have plugin to deal with such cases.
  If I use those plugins I end up with : 
  <code>project.jar</code>
  <code>project-sources.jar</code>
  <code>project-javadoc.jar</code>
  <code>project-tests.jar</code></p>
  
  <p>Is this the right way?</p>
  
  <p>Thanks!</p>
