Question

我将SceneBuilder与netbeans一起使用来创建一些场景。当我运行程序时，我不断收到此错误：

Caused by: java.lang.NullPointerException: Location is required.

我正在用正确的文件位置和软件包信息从主程序文件调用fxml文件。

我尝试使用绝对路径。我尝试将fxml移动到与主文件相同的包。我尝试删除fxml并重新开始。我尝试删除整个程序并重新开始。我有jfoenix-8.0.8 jar。这是来自主文件

public class MacroCounter extends Application {

    @Override
    public void start(Stage stage) throws Exception {     
        Parent root = FXMLLoader.load(getClass().getResource("scenes/FXMLDocument.fxml")); 
        stage.setTitle("Macro Counter");

        Scene scene = new Scene(root);

        stage.setScene(scene);
        stage.show();
    }

使用/scenes/FXMLDocument.fxml 我收到此错误：造成原因：javafx.fxml.LoadException：文件：/Users/ryanhoffman/Desktop/School%20Work/Applied%20Software/MacroCounter/dist/run1913970246/MacroCounter.jar！/scenes/FXMLDocument.fxml：13 代替获取空指针引起原因：java.lang.NullPointerException：必需的位置。

netbeans似乎正在移至文件所在的位置，但fxml无法正常工作。我认为它与此MacroCounter.jar有关！那是在文件路径中，但我真的不明白为什么。 MacroCounter.jar！/scenes/FXMLDocument.fxml：13

主文件运行时FXML加载异常。文件路径正确，stll失败
