Expansion Settings

Each NS project requires an expansionSettings.xml. This file contains all needed information to execute an expansion. It describes:

  • where to find the model files
  • where to generate the expanded artifacts
  • which expanders (expansion-resources) to use

A pom.xml Maven project file is also required to set up Maven. It should include the expanders-maven-plugin, which is used to run the expansion.
