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.

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.

Closing this as it's simply a matter of Google updating GAE to JPA 2.0

from spring-data-jpa.
