Repository Management with Nexus
21.10. Defining Custom Repository Types

When you need to introduce a custom repository type, you should implement the Repository interface. The following example extends the HostedRepository class and adds a repository type with the path prefix "sample".

Creating a Custom Repository Type Interface. 

package org.sample.plugin;

import org.sonatype.nexus.plugins.RepositoryType;
import org.sonatype.nexus.proxy.repository.HostedRepository;

@RepositoryType( pathPrefix="sample" )
public interface SampleRepository extends HostedRepository {
  String boo();
}

If you want to implement a custom repository type, you should reference the nexus-proxy module as dependency which contains the AbstractRepository class which is a useful super-class for repository implementations. To implement the SampleRepository interface, you can then extend the AbstractRepository as shown in the following example.

Creating a Custom Repository Type Implementation. 

package org.sample.plugin;

public class DefaultSampleRepository extends AbstractRepository
    implements SampleRepository {

  .... implement it

}

Your newly introduced repository type will appear under http://localhost:8081/nexus/content/sample/.
