Help me to solve the problem in github proxy repository

I need to make the github proxy repository. I thought I can solve by using nexus sonatype, but nexus doesn’t seem to support the github proxy repository. How can I solve this problem.
Hope someone with experience can help me.
Thank you.

If you’re trying to proxy a git repository hosted at github that I’m afraid that won’t work. Nexus Repo is a binary component manager, it isn’t a source code control system. It isn’t designed for that use case.
