missing com.zwitserloot dependency ?

`mvn verify` results in:

Could not resolve dependencies for project org.jboss.bot:jbossbot:jar:1.0.0-SNAPSHOT: Could not find artifact com.zwitserloot.json:json:jar:1.0

I assume this is manually built from git://github.com/rzwitserloot/com.zwitserloot.json.git since I cannot seem to find this artifact in maven central nor jboss repos ?
