Eclipse/java9-jigsaw: how to access javafx packages?

问题

My context:

• 9-ea-113 (that is javafx now fully modularized, without jfrt.jar)
• eclipse-neon-M6 with the current beta support for java9 (running on java8, if that matters)
• win7

Something simple like

import javafx.application.Application;

public class FirstApplication extends Application {
    //
}

doesn't compile because the javafx.xx packages are not found.

What to do?

回答1:

Edit the .classpath file of the project and add the entry below - seems to work.

  <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8">
     <accessrules>
       <accessrule kind="accessible" pattern="javafx/**"/>
     </accessrules>
  </classpathentry>
