The fastest way to get started developing AndroMDA plugins is by installing the AndroMDA Cartridge Maven Plugin.
To download and install the plugin into your maven plugin repository, first make sure you are pointing to the AndroMDA team server in your maven.repo.remote property (i.e. maven.repo.remote=http://www.ibiblio.org/maven,http://andromda.sourceforge.net/maven). Then type:
maven plugin:download -DgroupId=andromda -DartifactId=andromda-cartridge-plugin -Dversion=3.3
