收到错误：尝试启动 javaFX 应用程序时"JavaFX runtime components are missing, and are required to run this applicati

Question

我正在尝试使用 Maven 使用 Java 11 创建 JavaFX 项目。我已经在POM文件中添加了依赖项，但是当我尝试运行应用程序时，出现错误：

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

如果我使用 Java 8 SE 运行应用程序，它会启动并正常工作。

我查看其他SO帖子，但找不到解决方案。我试图创建新的主文件，然后调用应用程序(myApplicationClass.class，args(

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

但随后我收到此错误：

Exception in thread "WindowsNativeRunloopThread" java.lang.NoSuchMethodError: <init>

    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

我在使用 OpenJDK 版本 12 和 Oracle JDK 版本 12 时遇到了同样的问题。

作为临时解决方案，我恢复到Oracle JDK版本8。 这消除了错误。
