maven超级pom

一、超级pom简介

在maven的发行版本中都会有一个超级pom，超级pom是所有maven项目的父pom，所有项目都继承这个超级pom，在超级pom中配置有：

1. maven的构件和插件的中央仓库地址；
2. 项目构建过程中用到的一些默认目录；
3. 一个自带的profile；

二、超级pom路径

在maven本地仓库的如下位置：
org\apache\maven\maven-model-builder\3.0.4
打开该路径下的如下jar包：
maven-model-builder-3.0.4-sources.jar
在该jar包的如下路径下：
org\apache\maven\model\
可以找到超级pom：
pom-4.0.0.xml
