title: The import org.osgi cannot be resolved OSGI
body: <p>I created plugin project with only <code>Activator</code> class. </p>
  
  <pre><code>import org.osgi.framework.BundleActivator;
  import org.osgi.framework.BundleContext;
  </code></pre>
  
  <p>But I get this error: <code>The import org.osgi cannot be resolved.</code></p>
  
  <p>I downloaded the "Equinox OSGi R4 framework implementation" from <a href="http://download.eclipse.org/equinox/drops/R-Neon.2-201611241400/index.php" rel="nofollow noreferrer">Equinox Release Build: Neon.2</a></p>
  
  <p>Did copy/paste in ProgramFiles\eclipse\plugins and when I search the bundle in OSGi framework configuration it seems like it isn't there <a href="https://i.stack.imgur.com/SAOg8.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/SAOg8.png" alt="enter image description here"></a></p>
  
  <p>Clicking on "Add Required Bundles" doesn't seem to work.</p>
