Maven 3 Plugin API

 The API for Maven 3 plugins - composed of goals implemented by Mojos - development:

 * goal code extends {{{./apidocs/org/apache/maven/plugin/AbstractMojo.html}<<<AbstractMojo>>> base class}} that implements {{{./apidocs/org/apache/maven/plugin/Mojo.html}<<<Mojo>>> interface}},
