wildfly-swarm trying to add JPA fraction

Question

I am trying to add JPA into a simple wildfly-swarm Rest API. I ran around in circle trying to follow the JPA example of the github page with no luck [https://github.com/wildfly-swarm/wildfly-swarm-examples/tree/master/jpa My app is kind of a "hello world" REST API as am new to wildfly-swarm: Can I get a step by step instruction on how to set up persistence, in a kind of "hello world" project like mine? here is the repo https://github.com/desiby/swarm-rest

After adding JPA and H2 as a dependency and turning the "person" object into a persistence entity here is the error I get (same error after adding the hibernate dependency:
