Auto mirroring Nexus Proxy Repository

Question

Currently, we have a nexus hosted-repository remotely (in a different geographic location). We have a local-proxy-repository locally to the hosted-repository.

Whenever there are new versions of a few files added to remote-hosted-repository, the first request for the newly added file from the build system is downloading it to local-proxy-repository.

The problem I have now is that some of the files being added are really huge (say around 400 MB). Therefore the first build consumes lot of time to finish.

Is there a way we can poll on remote-hosted-repository and auto-mirror it ?

Answer 1

Nexus Professional 2.+ supports this as experimental feature of the Smart Proxy feature set. It is an experimental feature that is off by default, but should work just fine. Give it a go!

To turn it on go to "administration/capabilities". Check "show advanced" and then select the "smart proxy: subscribe" and enable preemptive fetch.

Update: as of Nexus 2.3 this is no longer deemed experimental and you can configure if for each repository that you proxy off.
