What is it?

Njord is a Maven 3 and Maven 4 extension that offers local staging, repository operations and repository publishing. More precisely, Njord is a Resolver 1.x and 2.x extension (is yet another RepositoryConnector) that is loaded via Maven extensions mechanism and extends Resolver. Njord does not mingle with your build at all.

Njord supports “templates”, that define repository properties. Based on template a repository (“artifact store” in Njord lingo) is created. And those repositories can be merged, redeployed, dropped, validated or published (and more coming).

For now, templates supported out of the box are:

To deploy to Njord repository, one can use the usual Resolve remote repository URL with protocol njord:. The examples below with the id:: prefix (repository ID) can be used by maven-deploy-plugin for -DaltDeploymentReposiotory, but in this case the id is really just a placeholder to fulfil the required syntax.

Example URIs:

• njord: - means “use default template and create a new store” that is release-sca.
• njord:snapshot - means “use template by that name and create a new store”, in this case snapshot
• njord:store:release-00001 - means “select existing store release-00001 and use that”, in this case store release-00001.

Basically by setting up your POM with distribution release repository using URL njord: and snapshot repository using URL njord:snapshot you are ready to use Njord. But, Njord is not intrusive, you can still use it by doing nothing in your project and just deploying with -DaltDeploymentRepository=id::njord: as well.
