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}},

 * {{{./apidocs/org/apache/maven/plugin/logging/Log.html}<<<Log>>> interface}} provides easy logging for the goal.

/**
 * Interface allows overriding default mojo execution strategy For example it is possible wrap some mojo execution to
 * decorate default functionality or skip some executions
 */
public interface MojosExecutionStrategy {

    /**
     * Entry point to the execution strategy
     *
     * @param mojos             list of mojos representing a project build
     * @param session           current session
