运行jar时出现JavaFx NullpointerException

Question

Heho社区， 当我在eclipse中运行它时，我创建了一个JavaFx应用程序并且每个工作都很好。但是当我将应用程序作为jar文件运行时，我得到以下错误。几天前，我有另一个控制器问题（可以解决）和一个“隐藏”的invocationTargetException，当出现另一个错误时，它出现在Eclipse的控制台中。我无法解决这个问题，我猜运行jar时出现的错误就是指。这是我的旧问题的链接：JavaFX Exception in Application constructor java.lang.reflect.InvocationTargetException

运行jar时的当前错误：

java.lang.NullPointerException

这是我的主要：

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) {
        try {
            //anLeitungLaden();
            FXMLLoader loader = new FXMLLoader();
            loader.setLocation(getClass().getResource("resources/Layout.fxml"));
            Pane pane = (Pane) loader.load();
            Scene scene = new Scene(pane);
            scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
            primaryStage.setTitle("Hashiwokakero");
            primaryStage.setScene(scene);
            primaryStage.setResizable(false);

            primaryStage.getIcons().add(new Image(Main.class.getResource("resources/Alien.png").toString()));
            primaryStage.show();

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

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

拜托，有人知道如何解决这个问题吗？我整天都在寻找解决方案，慢慢变得疯狂 - .-

编辑：当在Eclipse中触发错误运行时，也会发生此错误：
