title: The import org.eclipse cannot be resolved
body: <p>I cloned a git java project with Eclipse, but I get many errors because I cant resolve these imports:</p>
  
  <pre><code>import org.eclipse.ui.plugin.AbstractUIPlugin;
  import org.osgi.framework.BundleContext;
  </code></pre>
  
  <p>What should I do?</p>
  
  <p>I use Eclipse IDE for Java Developers, Version: Mars Release (4.5.0).</p>
  
  <p>Solution:
  The source was an eclipse plugin, and I needed JAVA EE Eclipse to compile and run it. Thanks for the help greg-449.</p>
