there is no reason for checking in jars into your repository tinkerpop stuff (release and snapshots) and everything else is available via maven repos so please consume these repos (e.g. sontaype oss repo for tinkerpop).
handle orientdb / graphdb / lib via maven do not checkin binaries.
remove all lib folders as they are obsolete
I see that in the module distribution you use the assembly plugin. Why do you still have ant in the boat? Is there any reason for not dropping all ant scripts and the lib /*.jar which are checked in?
We have most of the test case that run with "ant clean test". Would you like to contribute to move them to Maven?
