This is a limitation of AppEngine's datastore data access provider DataNucleus:
WARNING: Nested in org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'fooRepository': FactoryBean threw exception on object creation; nested exception is java.lang.UnsupportedOperationException: Dont yet support getMetamodel:
java.lang.UnsupportedOperationException: Dont yet support getMetamodel
at org.datanucleus.jpa.EntityManagerFactoryImpl.getMetamodel(EntityManagerFactoryImpl.java:532)
Ultimately, however it's because Spring Data JPA is using the metamodel
from spring-data-jpa.
Oliver Drotbohm commented
Right, Spring Data JPA requires JPA 2.0 and GAE only supports 1.0 currently. So don't see how we can get this fixed until Google supports the current specification version
from spring-data-jpa.

Actually not a limitation on DataNucleus at all, which has supported JPA2 for a long time (v2.1). It's a limitation in Google's GAE/J plugin for DataNucleus (which still uses DataNucleus v1.1)
from spring-data-jpa.
Oliver Drotbohm commented
Closing this as it's simply a matter of Google updating GAE to JPA 2.0
from spring-data-jpa.
