title: Find version number of certain plugins in Eclipse
body: <p>More specifically I need to write code so that I can find the Eclipse Version number (4.7.0). I can't look it up in a file (.eclipseproduct or about.mappings) and I need to make an API call. </p>
  
  <p>So I was wondering whether I'll be able to find out the version number of the plugin <code>org.eclipse.platform</code> by some Java program.</p>
