Why I can't install SFC through maven?

Hello everyone, I'm trying to set up an image of SFC from Scratch from this guide of ODL's wiki. It's almost two days that I'm facing the same error on the last part of building:

mvn clean install -Dmaven.test.skip=true

image description

After a lot of searching in here I've tried almost everything to make it work; but without success.

Some more informations about my build:

  • Java Version: 1.8 (Also tried 1.7)
  • Maven Version: 3.3.9 (Also tried 3.2.1)
  • Ubuntu: 16.04 LTS Server
  • Not any proxy, just a VM with Bridged Connection
  • Python Version: 3.4.1
  • ~/.m2/settings.xml from /opendaylight/odlparent/master/settings.xml

I really appreciate any help you can provide, Mike
