eclipse中的Maven项目可以作为java应用程序运行,但jar文件不能正常运行

eclipse中的Maven项目可以作为java应用程序运行,但jar文件不能正常运行,java,css,eclipse,maven,Java,Css,Eclipse,Maven,我已经搜索过了,也许这个答案和我的问题很相似,但我还是不明白 我的项目结构: 包装学 ----src/main/java --------用户界面 ------------Init.java ----src/main/resources --------css ------------Init.css --------图像 ------------icon.png package ui; import javafx.application.Application; import javafx.

我已经搜索过了,也许这个答案和我的问题很相似,但我还是不明白

我的项目结构:

包装学
----src/main/java
--------用户界面
------------Init.java
----src/main/resources
--------css
------------Init.css
--------图像
------------icon.png

package ui;

import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.stage.Stage;

public class Init extends Application{

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

    @Override
    public void start(Stage primaryStage) throws Exception {
        Button button = new Button();
        button.setPrefSize(50, 50);
        button.setId("button");
        Group group = new Group();
        group.getChildren().add(button);
        Scene scene = new Scene(group,300,300);
         scene.getStylesheets().add(getClass().getResource("../main/resources/css/Init.css").toExternalForm());
        primaryStage.setScene(scene);
       primaryStage.show();
    }

}
当我选择RunAs->java应用程序时,它工作得很好

但是当我运行maven包制作的jar时,它显示 (Init:23是scene.getStylesheets().add(getClass().getResource(“../main/resources/css/Init.css”).toExternalForm());)

我的问题是:如何使jar正常运行。谢谢大家!

maven shade插件将只复制maven依赖项。您可能手动将jfxrt.jar添加到构建路径中,因此它在eclipse中不会丢失。您可以使用maven dependency插件复制依赖项,并尝试更改着色jar中的清单以包含复制的依赖项。或者,使用shade插件,您可以添加jfxrt.jar硬编码idk-see以获取引用i changed scene.getStylesheets().add(getClass().getResource(“../main/resources/css/Init.css”).toExternalForm();添加(getClass().getResource(“/main/resources/css/Init.css”).toExternalForm());那就行了
