eclipse - 为什么 Eclipse 在运行我的 JavaFX 应用程序时会显示这些错误？

Question

在此处输入图像描述

请帮我解决这个日食错误。实际上问题是，当我尝试在 Eclipse IDE 编译器中启动 javafx 时，会显示这些错误，如图所示。虽然 JavaFx libaray 是导入的代码也是正确的，但为什么我仍然会收到这样的错误。请帮我解决这个问题。

import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

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

    @Override
    public void start(Stage primaryStage) {
        primaryStage.setTitle("Hello World!");
        Button btn = new Button();
        btn.setText("Say 'Hello World'");


        StackPane root = new StackPane();
        root.getChildren().add(btn);
        primaryStage.setScene(new Scene(root, 300, 250));
        primaryStage.show();
    }
