Maven, by design, is a plug-in execution framework. Plugins are used to accomplish a goal or many goals. They can be used for such things as lifecycle management, packaging, and reporting.
Maestro comes with approximately 38 pre-configured plugins. A comprehensive, detailed list of the available plugins can be found at http://maven.apache.org/plugins/. There are also many plugins available at the Mojo project at Codehaus. To see the most up-to-date list, browse the Codehaus repository at http://repository.codehaus.org/, specifically the org/codehaus/mojo sub-folder. In addition, there are a few other projects that provide pre-configured Maven 2 plugins as shown below.
