Provide a feature enhancement which will help using nexus easier.

**What's it about?**
When the users build the image which needs pulling the dependence package from maven,they need the nexus to save the package.So we'd better provide a feature to help users to do it.

/area devops
/kind feature-request

Clarify the proposed Nexus support for builds that pull dependency packages from Maven, since the issue does not identify files, entry points, or expected behavior. Define the user workflow and acceptance criteria before locating the relevant build or dependency-management code.
