使用 Ant 构建 JavaFX 应用程序

Question

我一直在寻找解决我的问题的方法，我没有找到任何可以帮助我的东西，我需要从我的应用程序创建 exe，当我编译它时它工作，但是当我尝试生成exe 它给我一个例外：

MainApp.class

package br.nivelamento;

public class MainApp extends Application {

    private Stage primaryStage;
    private BorderPane rootLayout;

    @Override
    public void start(Stage primaryStage) {
        this.primaryStage = primaryStage;
        this.primaryStage.setTitle("NivelamentoApp");
        setUserAgentStylesheet(STYLESHEET_CASPIAN);
        initRootLayout();
    }

    public static void main(String[] args){
        MainApp.launch(MainApp.class, args);
    }
    public void initRootLayout() {
        try {
            // Carrega o root layout do arquivo fxml.
            FXMLLoader loader = new FXMLLoader();
            loader.setLocation(getClass().getResource("view/RootLayout.fxml"));
            rootLayout = (BorderPane) loader.load();

            // Mostra a scene (cena) contendo o root layout.
            Scene scene = new Scene(rootLayout);
            primaryStage.setScene(scene);

            // Dá ao controller o acesso ao main app.
            RootLayoutController controller = loader.getController();
            controller.setMainApp(this);

            //liga o hibernate
            JpaUtil.getEntityManager();

            primaryStage.show();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

经过多次尝试终于成功了，错误在 loader.setLocation (MainApp.class.getResource ("view / RootLayout.fxml")); RootLayout.fxml 看到不是真名真名是rootLayout.fxml 修复大写字符就解决了我的问题
