maven-shade-plugin将不包含依赖项

Question

我有一个令人毛骨悚然的问题。我正在尝试使用maven-shade-plugin将带有嵌入式tomcat服务器的spring mvc应用程序打包到单个jar中。我已经尝试过类似的任务。曾经尝试对我的pom文件使用类似的配置。不幸的是，打包后的罐子只包含我创建的类。清单确实提到了所有依赖项。我认为这可能是Maven的问题，但是尝试了另一个项目，并且插件似乎正常工作。这是我的POM的相关片段：

Answer 1

删除标签<pluginManagement></pluginManagement>，并保留其余部分，否则将无法正常工作。

技巧只是因为pluginManagement顾名思义是插件的管理，通常是版本，有时是配置。这意味着在pluginManagement中定义的插件将永远不会执行。

[如果您希望使用<plugins></plugins>来执行插件
