【中文标题】Maven 遮罩插件不会遮蔽工件中的依赖项【英文标题】：Maven shader plugin doesn't shade dependencies in artifact 【发布时间】：2019-07-21 12:25:08 【问题描述】：

好的，我已经尝试了更多的依赖项，似乎我拥有的每个依赖项都没有被隐藏到我的 jar 文件中。为什么会这样？

我创建了具有不同组和工件 ID 的不同项目，但我创建的每个项目都遇到相同的问题。

我得到NoClassDefFoundError，因为我想做的一切都取决于依赖项之一。 我已经尝试了很多东西编辑 pom.xml 和 TestPlugin.iml 在很多方面仍然没有，只有依赖 bukkit/paper 依赖的东西工作得很好，我现在一无所知。

使用了 mvn clean install 和 mvn dependency:tree，它运行良好，但是当我把它放在服务器的插件中时，它就坏了。

关注此tutorial 并更改了我必须更改的所有内容以更改相同的结果。

【问题讨论】：

感谢您的加入。看来这与maven-shade-plugin如何配合创建插件有关。我不确定这是如何工作的，但我会在那里寻找问题。代码生成可能在 IntelliJ 中起作用的原因是您复制了配置。您还使用了jooq-codegen-maven 插件，这对于您的程序代码生成器配置来说似乎是多余的。 我确实通过maven使用了代码生成器，直到我找到了程序化代码生成器。 还有问题是我的设置方式还是我可能做错了什么？ 我不知道。我告诉了你我的怀疑，但你必须最终验证。 更改了配置，而不是为其创建方法，而是将其放入 onEnable 并删除了 maven code-gen 插件仍然是同样的问题。 【参考方案1】：

最终用这段代码修复了它：

【讨论】：

以上是关于Maven 遮罩插件不会遮蔽工件中的依赖项的主要内容，如果未能解决你的问题，请参考以下文章

使用提供的工件作为 Maven 插件依赖

为啥有时会跳过 maven 依赖项中的版本号？

如何找出是不是在 Maven 应用程序中使用了依赖项中的任何类？

Maven 阴影插件重定位不更新资源文件中的条目

可以使Maven构建包含依赖项中的.class文件[重复]

为啥即使我的 maven 依赖项中有第三方依赖项，也只需要 OSGi 容器中的第三方依赖项？
