无法在eclipse中加载fxml文件

Question

所以我在JavaFX中有非常基本的代码（在eclipse上安装了e（fx）clipse）但我似乎无法加载我的fxml文件。我最近一直在使用一些JavaFX，但仅使用纯代码形式，我试图切换到使用带有SceneBuilder的fxml，但我似乎无法运行最简单的应用程序。我很感激有人指出我做错了什么。我得到以下异常：

        Parent root = FXMLLoader.load(getClass().getResource("Merger.fxml"));
        primaryStage.setTitle("Image Merger");
        primaryStage.setScene(new Scene(root));
        primaryStage.show();
    }

    public static void main(String[] args) {
