Question

我正在尝试使用Maven使用Java 11创建JavaFX项目。我已经将依赖项添加到POM文件中，但是当我尝试运行该应用程序时出现错误：

JavaFX runtime components are missing, and are required to run this application.

如果我使用Java 8 SE运行该应用程序，它将启动并正常运行。

我查看了其他SO帖子，但找不到解决方案。我试图创建一个新的主文件，然后调用Application（myApplicationClass.class，args）

public class Main {
    public static void main(String[] args) {
        Application.launch(Launcher.class, args);
    }
}

但随后出现此错误：

Exception in thread "WindowsNativeRunloopThread" java.lang.NoSuchMethodError: <init>
    at com.sun.glass.ui.win.WinApplication.staticScreen_getScreens(Native Method)
    at com.sun.glass.ui.Screen.initScreens(Screen.java:412)

    at java.base/java.lang.Thread.run(Thread.java:834)

这是我的启动器类：

public class Launcher extends Application {

   public static void main(String[] args) {
       launch(args);
   }

   @Override
   public void start(Stage primaryStage) {
       Scene rootScene = new MainMenu();
       AppContext.init(primaryStage, rootScene);

       primaryStage.setResizable(false);
       primaryStage.show();
   }

这是我的POM.xml

Answer 1

我同时使用OpenJDK 12版和Oracle JDK 12版遇到相同的问题。

作为一个临时解决方案，我恢复了Oracle JDK版本8。这消除了该错误。

收到错误消息：尝试启动我的javaFX应用程序时，“缺少JavaFX运行时组件，这些组件是运行此应用程序所必需的”
