This configuration will take into account the model described in the file src/main/mdo/myModel.mdo in version 1.0.0. It will execute the following goals in the generate-source phase:

• java which will generate Java beans from the model,
• xpp3-reader which will create an XPP reader for the model.

The generated Java sources will be located in the target/generated-sources/modello folder (or in the folder set by the outputDirectory parameter), which will be added as a source folder to the project build cycle.

During the pre-site phase, it will execute the following goals:

• xdoc which will generate a documentation of the model in the target/generated-site/xdoc folder, which will in turn be processed to output in the standard site, during the site phase,
• xsd which will generate an XML Schema for our model in the target/generated-site/resources/xsd folder (set by the outputDirectory parameter), which will in turn be copied in the standard site, during the site phase.
