 In order the understand how inheritance works in Maven there are a few notions that you must be familiar with:

 * The maven super model

 * how parent poms are processed

 * the order in which elements in the POM are overridden

 * minimum element-set for a valid project pom


Maven super model

 Inheritance is recursive in Maven but there is a special model which is the implicit super parent in the lineage
 of models you may specify:

          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-release-plugin</artifactId>
          <version>2.0-beta-4</version>
          <configuration>
            <!-- This element will be overridden by children -->
            <tagBase>https://svn.apache.org/repos/asf/maven/pom/tags</tagBase>
            <useReleaseProfile>false</useReleaseProfile>
            <goals>deploy</goals>

 that belong to the same group, the project level allows configuration management at
 the project level, and the user level allows users to override settings on
 the site level, group level and project level.

* Site configuration

 At the site level all configuration is achieved by tweaking the various files that
