Build Identifier: 2.2.0-RC4

In case deriving an entity by another entity that contain to different projects, generating the metamodel results a NullPointerException.

In order to build the projects maven is used.

---
When using 2.1.2 the metamodel is generated incorrectly. The reference to the parent entity does not exist in the child entity. But there is no NullPointerException when generating the metamodel.


Stacktrace:
