Maven shade插件重定位和捆绑不工作

在我的POM.xml中，我使用了maven-shade插件并重新定位了httpClient依赖关系。但是当我使用mvn dependency：tree打印依赖关系树时，我仍然可以在树中看到httpClient库，如下所示。这是为什么发生。任何帮助将不胜感激。Maven shade插件重定位和捆绑不工作

两件事情 -

你应该知道做什么搬迁不是 “...搬迁HttpClient的相关性”，但作为source建议 -

如果超级JAR被重用作其他项目的依赖项，直接包含来自中的构件依赖项的类。超级JAR可能导致类加载冲突，这是由于类路径上的重复类造成的。为了解决这个问题，可以重新定位其中获得包含在阴影神器类，以创建自己的字节码的私人副本
当您执行mvn dependency:tree它会显示所有的依赖（直接和包括在您的项目中。相反，行家遮阳插件

灯罩：灯罩被绑定到包相和用于创建一个阴影罐子。

进一步重命名或优化依赖关系。这里有云的细节Maven Shade Plugin -

此插件提供打包的神器在尤伯杯罐子，包括它的依赖和遮阳的能力 - 即重命名 - 一些依赖性的包。

该依赖不会从原始POM中删除，因此dependency:tree的行为是正确的。

阴影插件还会生成一个新的POM（dependency-reduced-pom.xml），其中阴影依赖关系从<dependencies>部分中删除。这看起来像你之后的那个。
