Question

What are the compatible dependencies for Google App Engine (GAE) DataNucleus? After running mvn appengine:devserver my app’s configuration keeps throwing an error below:

I’m in the process of migrating an old App Engine code from OReilly to Maven.

main > resources > META-INF > persistence.xml
