我在我的应用程序中使用 Synthetica Look and Feel，它在 Eclipse 上运行良好。但是当我导出 Jar 文件并执行它时，我得到了这些错误：

我不知道问题到底出在哪里。这是我应用 Synthetica Blue Steel 外观和感觉的方式：

try 
    {
      UIManager.setLookAndFeel(new SyntheticaBlueSteelLookAndFeel());
      UIManager.put("Synthetica.rootPane.titlePane.title.center", true);
      UIManager.put("Synthetica.translucency4DisabledIcons.enabled", true); 

    } 
    catch (Exception e) {}

我认为您导出 jar 文件的方式不正确。

尝试将 jar 导出为 Runnable jar 文件。
按照以下步骤将您的应用导出为可运行的 jar。
1) 从文件菜单中选择导出。
2) 选择Java->Runnable JAR 文件
3) 选择启动配置，即你的主类。
4）如果要将物质库文件打包到自己的jar中，则库处理的前两个选项和第三个选项（将所需的库复制到生成的jar旁边的子文件夹中）如果要将生成的jar文件和物质分开库。
5）按完成。

我希望这能解决你的问题。:)

请查看它找不到 sun/swing/plaf/synth/SynthUI 库的错误。在开发模式下，您将该 jar 文件包含在 eclipse 库中，但是当您创建 jar 文件时，您不包含 Synthui 主题 jar。将 Synthui jar 文件放在 jar、ext/ 文件夹中，它可以正常工作
