未设置位置[重复]

我在尝试运行代码时遇到了这个错误,加载一个fxml文件是一个简单的javafx代码,我尝试了我在这里找到的解决方案,但是没有什么对我有用。抱歉,如果格式不是很好,这是我在这里的第一个帖子,如果我正在扼杀语言,英语不是我的第一语言。事先谢谢!

    this.primaryStage = primaryStage;
    this.primaryStage.setTitle("CineTudo");

    initRootLayout();

        //Carrega o layout root do arquivo fxml
        final FXMLLoader loader = new FXMLLoader(MainApp.class.getResource("/resources/RootLayout.fxml"));
        rootLayout = (BorderPane) loader.load();
