title: Error resolving all javafx imports
body: <p>I have a problem importing an existing project.  </p>
  
  <pre><code>    import javafx.application.Application;
      import javafx.fxml.FXMLLoader;
      import javafx.scene.Parent;
      import javafx.scene.Scene;
      import javafx.stage.Stage;
  </code></pre>
  
  <p>The error: The import javafx cannot be resolved.</p>
  
  <p>I use Java 8 OpenJDK amd64 as the JRE System Library. Also i have no idea which version of java the primary version had if you would refer to <a href="https://stackoverflow.com/questions/29525483/some-javafx-imports-cannot-be-resolved-in-eclipse">this</a> solution. I use the newest version i can.
  <br>Any ideas?
  <br>Thanks</p>
