Fix NotFoundException

✅ Solution

The "NotFoundException" in nexus-repository often arises from a missing or misconfigured plugin or component, particularly when custom extensions are involved. Ensure the relevant plugin is correctly installed, activated, and configured; verify its ID matches the expected value in the Nexus Repository configuration and that any backing OSGi bundles are properly deployed and resolved. Reinstalling or redeploying the plugin might be necessary if the configuration or its associated files were corrupted.
