Sorry for the inconvenience. Nexus Server (maven.glassfish.org) will
be down from 6-7pm today as we prepare to upgrade the system.
How does it effect you?
You will not be able to compile GFv3 using a clean Maven local
repository or use "mvn -U..." since Nexus server manages all the
repositories referenced in GFv3. This means that downloading artifacts
from remote repository will fail. Please compile v3 with the "-o" or
"--offline" option:
"mvn -o install"
