grails/ivy proxy exclusions?

I need to connect to a nexus repo of mine, but I'd also like the ability to grab files from the the central maven repository. If I use grails add-proxy, there's no way to set an exclusion list.

I'm behind a corpora开发者_如何学Gote proxy, and the nexus repo is within the proxy.

What should I do?

In Nexus create a repository group includes the central repository. In that way Nexus is a "one stop shop" for all your dependencies.

More efficient and protects you against an internet outage. (Nexus will cache the central jars)
