Beanshell plugin

A Beanshell mojo uses same javadoc tags as a Java mojo with javadoc tags.

Sample script content:

/**
 * Touches a test file.
 *
 * @goal touch
 * @requiresDependencyResolution=test
 * @deprecated Don't use!
 * @since 1.2
 */

import org.apache.maven.plugin.Mojo;
import org.apache.maven.script.beanshell.BeanshellMojoAdapter;
import org.codehaus.plexus.util.FileUtils;



execute()
{
    logger.info( "Executing beanshell mojo..." );
    FileUtils.fileWrite( outDir + "/" + name, "This is a Beanshell test" );
}

/**
 * Output directory for files.
 *
 * @parameter expression="${project.build.directory}"
 * @required
 */
setOutDir( file )
{
    outDir = file;
}

/**
 *
 *
 * @parameter expression="${name}"
 * @required
 */
setName( name )
{
    name = name;
}

return new BeanshellMojoAdapter( (Mojo) this, this.interpreter );
