Pulling oracle jdbc driver from local nexus repository through ivy -> tries to hit external source?

I'm behind a proxy, and I'm trying to grab a jar from my local nexus repository that I added manually. Why does grails/ivy try to connect outward when I try to download the jar?

This mysteriously no longer happens. I did switch back to 1.3.6 for other reasons, but I'm not sure why this ever occurred.
