Question

我在使用工件打开程序时遇到了问题。

所以我制作了一个带有几张图片的JavaFX应用程序。现在我正在尝试在* .jar文件中启动应用程序，但它不起作用。我用想法构建了jar文件，并且包含了所有内容。我在这里遇到了错误：

我有一个名为ImageRessources的类，并且有几行代码如下：

public class ImageRessources {
    public static final Image _500DominosImage = new Image(String.valueOf(ImageRessources.class.getResource("../Images/500d.png").toExternalForm()));
}

我只复制了一行，其他图片以同样的方式包含在内。

你能帮助我获得一个可启动的jar文件吗？
