<packaging>pom</packaging> 是一个标签，用于指定项目打包方式为Maven的POM（Project Object Model）文件。它表明该项目的构建和打包方式是由Maven来管理的。
在Maven中，POM文件是项目的基本单位，包含了项目的配置信息、依赖关系、构建脚本等。通过使用<packaging>pom</packaging>标签，可以告诉Maven该项目的构建和打包过程是由POM文件来定义的。
通常，一个Maven项目会有一个名为pom.xml的文件，其中包含了项目的POM信息。这个文件是Maven项目构建和打包的基础，通过在POM文件中配置各种元素和插件，可以控制项目的构建流程、依赖管理、打包方式等。
总之，<packaging>pom</packaging>标签用于指定项目打包方式为Maven的POM文件，以告诉Maven使用POM文件来管理项目的构建和打包过程。
`<packaging>pom</packaging>`用于指定 Maven POM 项目的打包类型。它表示该项目是一个父模块项目，其中包含可被子模块继承的公共配置、依赖和插件。此类项目不会生成可执行的构件（例如，jar、war），而是作为管理多个项目共享配置和依赖项的中心点。
