学习笔记——Maven超级POM

2014-07-04：更新如何在安装程序中找到超级pom文件。
Maven有一个超级POM，所有的POM均继承此文件。
你可以使用解压工具打开jar文件$M2_HOME/lib/maven-model-builder-x.x.x.jar，然后访问路径org/apache/maven/model/pom-4.0.0.xom
Ps: maven2中为org/apache/maven/project/pom-4.0.0.xml
该文件定义如下：
<project>

  <modelVersion>4.0.0</modelVersion>

  <repositories>

    <repository>

      <id>central</id>

      <name>Central Repository</name>

      <url>http://repo.maven.apache.org/maven2</url>

      <layout>default</layout>

      <snapshots>

        <enabled>false</enabled>

      </snapshots>

    </repository>

  </repositories>

  <pluginRepositories>

    <pluginRepository>

      <id>central</id>

      <name>Central Repository</name>

      <url>http://repo.maven.apache.org/maven2</url>

      <layout>default</layout>

      <snapshots>

        <enabled>false</enabled>

      </snapshots>

        <updatePolicy>never</updatePolicy>
