Hey,

I didn't get the part of version purging with Oak jar. May be something I don't know.....
But, you can do the version purging using the Purge tool available with in AEM.
http://<server>:<port>/etc/versioning/purge.html

Also, as described in above comment, please make sure to create purge configuration.

Hope this helps.
