如何使用Maven构建独立的SWT GUI？

Question

在这个howto https://www.eclipse.org/swt/eclipse.php有一个很好的指导，如何用Eclipse构建一个基于SWT的GUI。 现在，我想与Maven组装相同的项目。通过使用pom.xml的结尾，我得到以下错误：

看起来像一个或多个您当地的.m2 Maven仓库中的罐子被损坏（jar-with-dependencies试图首先解开所有的依赖关系，以便将它们捆绑在同一个罐子中）。

不幸的是，错误信息并没有说明哪个。

您可以：

• 删除您.m2库的完整内容，并依靠Maven的重新下载他们（.m2库中找到，在Windows安装程序，在您的当前用户文件夹;例如对我来说这是位于C:\Users\Andrei\.m2）
• 重新运行您的版本与-X选项，其中应该提供有关哪个特定jar导致问题的更多细节。那么你只能删除那一个。

除非你在.m2文件夹中有任何自定义install S，我建议选择1
