Overall the Maven Settings integration in Nexus allows you to maintain multiple settings template files on the central Nexus server. You can configure settings files for different use cases like e.g.,
- referencing a repository group containing only approved components in the mirror section for your release or QA builds,
- providing an open public group mirror reference to all of your developers for experimentation with other components.
By using the Nexus M2Settings Maven Plugin you can completely automate initial provisioning and updates of these settings files to your users.
