Java外汇'cannot find symbol'

Question

我是 java 和 java fx 的新手，我正在尝试创建一个简单的 window 但我一直收到错误消息

java: cannot find symbol
  symbol:   class Group
  location: class sample.Main

这是我的代码：

package sample;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

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


    @Override
    public void start(Stage primaryStage) throws Exception{
        Group root = new Group();
        Scene scene = new Scene(root);


        primaryStage.setScene(scene);
        primaryStage.show();

    }




}
