The Mojo Executor provides a way to to execute other Mojos (plugins) within a Maven plugin, allowing you to easily create Maven plugins that are composed of other plugins.

Downloads

You can download the jars, source, and javadocs from the Maven 2 repository:

http://twdata-m2-repository.googlecode.com/svn/org/twdata/maven/mojo-executor/

Example Usage

This is how you would execute the "copy-dependencies" goal of the Maven Dependency Plugin programmatically:

executeMojo(
    plugin(
        groupId("org.apache.maven.plugins"),
        artifactId("maven-dependency-plugin"),
        version("2.0")
    ),
    goal("copy-dependencies"),
    configuration(
        element(name("outputDirectory"), "${project.build.directory}/foo")
    ),
    executionEnvironment(
        project,
        session,
        pluginManager
    )
);

The project, session, and pluginManager variables should be injected via the normal Mojo injection:

/**
 * The Maven Project Object
 *
 * @parameter expression="${project}"
 * @required
 * @readonly
 */
protected MavenProject project;

/**
 * The Maven Session Object
 *
 * @parameter expression="${session}"
 * @required
 * @readonly
 */
protected MavenSession session;

/**
 * The Maven PluginManager Object
 *
 * @component
 * @required
 */
protected PluginManager pluginManager;
