Problèmes avec l'exécution de DataNucleus JPA avec GAE / Java
J'ai un problème avec le fait que DN fonctionne avec App Engine en ce moment, l'erreur générée lors de la mvn clean install est:

Pourquoi utilisez-vous des pots très anciens et incohérents ?
Le pot "datanucleus-jpa" est si ancien qu'il n'a pas été utilisé depuis très longtemps AFAIK (tous les pots API sont de la forme datanucleus-api-XXX et l'ont été depuis longtemps). Peut-être prendre du recul et utiliser quelque chose de cohérent serait un début. Google définit les pots pour GAE JPA (ce que vous utilisez) ici. https://code.google.com/p/datanucleus-appengine/wiki/Compatibility
