应用程序启动方法 java.lang.reflect.InvocationTargetException 中的异常

Question

我正在尝试运行我的 Java 应用程序，但它显示此错误：

应用程序启动方法异常 java.lang.reflect.InvocationTargetException

package application;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;

import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;


public class TipCalculator extends Application {
    @Override
    public void start(Stage stage) throws Exception {
        Parent root =
                FXMLLoader.load(getClass().getResource("./Sample.fxml"));
        Scene scene = new Scene(root); // Attach scene graph to scene
        stage.setTitle("Tip Calculator"); // Displayed in window's title bar
        stage.setScene(scene);
        stage.show(); // Display the stage
        // Attach scene to stage
    }

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

这是我的文件和错误信息。我正在使用 Eclipse IDE：

Exception running application application.Main

解决方案：

我将这些功能添加到我的场景构建器中。这就是为什么它没有检测到功能并出现错误的原因。
