How to use datanucleus's enhances within maven in eclipse kepler?

Question 1

Well i simply changed all versions to the latest 4.0.0-m2 when I wanted to use it. Can't get simpler.

Question 2

Thanks to Neil's suggestion to check datanucleus's samples, here is a functioning POM file with JDO enhancer configured:
