Tests failure in MDSAL southbound plugin



I am going through this wiki page, but after I execute "mvn clean install" in southbound directory I get errors below (Note: I took just the first error because all of them are related). It looks like this artifact is missing, any idea on how I should go about solving this? Thanks
