You have a JPA Project X. Enums are defined in Project Y. JPA entities in
Project X are referencing these enums from Project Y. 

Generate DDL from entities will get the following error:

If you move these enums into the JPA Project X along with the entities
referncing them it works fine and DDL is generated without any problems. 
Looks like the Entity generating tool cannot identify project references. 

Note this problem is only with enums, It works fine with other types referenced
from external projects.


Reproducible: Always
