我有一個JavaFX項目包含FXML文件及其控制器和主類Jar文件將無法運行後生成的神器 - JavaFX的

Project Scource

程序完美的作品在IDE「的IntelliJ」 但是當我嘗試製作工件並構建它時,jar文件就不會運行「當然安裝了JRE」

我嘗試了很多方法來構建工件,所以是否有構建jar文件的特定方法FXML文件?

主類含有這種 「FXML裝載機」

public class Main extends Application { 

    @Override 
    public void start(Stage primaryStage) { 

     Parent root = null; 
     try { 
      root = FXMLLoader.load(getClass().getResource("/Sample/MainLayout.fxml")); 

      primaryStage.setTitle("Estimated Download Time"); 
      primaryStage.setScene(new Scene(root, 764, 600)); 
      primaryStage.getIcons().add(new Image(getClass().getResourceAsStream("Logo.png"))); 
      primaryStage.resizableProperty().setValue(Boolean.FALSE); 
      primaryStage.show(); 

     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 
    public static void main(String[] args) {launch(args);} 
}

「的jar文件就不會跑」。究竟發生了什麼?你有例外嗎?如果沒有,您是否嘗試過從命令行運行jar文件來查看它是否以這種方式生成堆棧跟蹤? –

我實際上得到java.lang.reflect.InvocationTargetException 例外在應用程序啓動方法 但程序完美地在IDE上運行! – AhmadMujahid

因此,在問題中發佈完整的堆棧跟蹤。 FXML文件的路徑可能不正確,或者FXML文件未被部署到jar文件。 –

我解決了從FXML裝載機剛剛刪除軟件包名稱問題

代替
root = FXMLLoader.load(getClass().getResource("/Sample/MainLayout.fxml")); 

我刪除了包名「樣本」,所以它成了這個

root = FXMLLoader.load(getClass().getResource("MainLayout.fxml"));
