maven---------pom配置文件标签的含义

自己在学习的过程中，遇到不了解maven标签含义的情况，经翻阅相关资料，在某培训机构培训课程中找到一下内容！

pom.xml是Maven项目的核心配置文件，位于每个工程的根目录，基本配置如下：

<project> ：文件的根节点.
<modelversion > ：pom.xml使用的对象模型版本
<groupId > ：项目名称，一般写项目的域名
<artifactId > ：模块名称，子项目名或模块名称
<version > ：产品的版本号 .

<packaging > ：打包类型，一般有jar、war、pom 等
<name > ：项目的显示名，常用于Maven 生成的文档。 
<description > ：项目描述，常用于Maven 生成的文档

<dependencies> ：项目依赖构件配置，配置项目依赖构件的坐标

<build> ：项目构建配置，配置编译、运行插件等。

附一份父工程pom文件：
