Example: Pulling,_Hacking,_and_Pushing_the_Code_from_the_CLI - Maven Build Fails...

Trying to follow the example in link:

https://wiki.opendaylight.org/view/OpenDaylight_Controller:Pulling,_Hacking,_and_Pushing_the_Code_from_the_CLI

Code pulled ok from Git...

Cloning into 'controller'...
remote: Counting objects: 33285, done

However - Running "mvn clean install" results in buid failure -
See attched log.

running nicely in MavenLandia and then we get;

:
:
[ERROR] The build could not read 1 project -> [Help 1]
[ERROR]
[ERROR] The project org.opendaylight.controller:config-parent:0.3.0-SNAPSHOT

Any ideas why the build fails would be appreciated...
I simply pulled the code following Wiki advice and tried to do maven build.
surprised to see it failed etc.
