title: Building an eclipse plugin. What dependency and which class could I extend to implement warning signs in Java and Effective pom files for a project?
body: <p>I am a bit new to eclipse plugin development. My requirement:</p>
  
  <p>I want to show warning signs(like screenshot attached) in the <strong>import statements Java files and effective pom files of Java projects</strong> based on some parameters.</p>
  
  <p>Assuming eclipse already has some classes and functions for this, I would like to know <strong><em>what dependencies I could add in my Manifest file of my Eclipse Plugin and which class I could extend and functions I could use to implement my requirement?</em></strong></p>
  
  <p>Any help would be very much appreciated. Thank you.</p>
