What I want is a runnable jar for whole project, but the maven is generating one runnable jar in the client module.我想要的是整个项目的可运行 jar，但 Maven 正在客户端模块中生成一个可运行的 jar。 Is there any way to generate one for the project rather one for every module?有没有办法为项目生成一个而不是每个模块一个？ If no then what is the purpose of declaring one parent pom for the project?如果不是，那么为项目声明一个父 pom 的目的是什么？

Answer 1

You cannot generate a jar from the parent POM.您不能从父 POM 生成 jar。 The parent POM is used to configure common plugins and dependency management.父 POM 用于配置常用插件和依赖项管理。 Furthermore, it specifies the groupId and the version.此外，它还指定了 groupId 和版本。

If you need a runnable jar, you need a dedicated module for that in which you build the runnable jar with either the assembly plugin or the shade plugin.如果你需要一个可运行的 jar，你需要一个专门的模块，你可以在其中使用程序集插件或 shade 插件构建可运行的 jar。
