How to deploy an already deployed build to another nexus repository?

Question

We have a nexus repository environment that serves for multiple projects. Each project has a repository group which includes

• 3rdParty
• snapshot
• test (release typed repo)

Projects prepare builds for testing which are deployed on test repository. What we would like to do is to re-deploy a specific version, which is already deployed on test repository, to a Releases repository on another nexus instance. By this way only tested builds can be reached by customers.

Is there a way to do that without performing another build? Some builds may take up more than 3 hours and also it is risky to perform another build. I've searched and come up with wagon plugin but I am not sure about it. This operation should also perform skip/merge capability (may be fail never?). Because for a bug-fix release, most of the artifacts may not be changed. Thus; skipping those artifacts will save time in delivery.

Below scenario would be perfect:

1. Build the project and deploy to the test repository
2. Perform tests using test repository
3. Tests passed, re-deploy system version 1.0.1 (including child components) to releases repository.
4. Customer can only see tested versions from releases repository (1.0.1, 1.0.7 etc)

Notes:

• using snapshot for test builds is not an option :(
