How can I extends already existing interfaces?

[onacit]

What steps will reproduce the problem ?

Steps to reproduce the behavior:

1. Predefine repository interfaces (in an upstream module)
2. (In a downstream module) extends EntityGraphJpa... interfaces.
3. The notorious findOne problem

Detailed scenaio

I have an upstream module which defined mapped superclasses and no-repository-beans.

@MappedSuperclass
public abstract class MappedSome<T extends Some<T>> {
}

@NoRepositoryBean
public interface MappedSomeRepository<T extends MappedSome<T>, Long> {
}

An I tried, with my down-stream module like this.

@Entity
public class Some extends MappedSome<Some> {
}

@Repository
public interface SomeRepository
        extends MappedSomeRepository<Some>,
                EntityGraphJpaRepository<Some, Long>,
                EntityGraphJpaSpecificationExecutor<Some> {
}

And I got this.

Caused by: java.lang.IllegalArgumentException: Failed to create query for method public abstract java.util.Optional com.cosium.spring.data.jpa.entity.graph.repository.EntityGraphJpaSpecificationExecutor.findOne(org.springframework.data.jpa.domain.Specification,com.cosium.spring.data.jpa.entity.graph.domain2.EntityGraph); No property 'findOne' found for type 'AdDaBookingDefaultSetting'

Oh. I neve forget the configuration.

@EnableJpaRepositories(
        repositoryFactoryBeanClass = com.cosium.spring.data.jpa.entity.graph.repository.support.EntityGraphJpaRepositoryFactoryBean.class)
@Configuration
@Slf4j
// https://github.com/Cosium/spring-data-jpa-entity-graph
class __DataJpaEntityGraphConfiguration {

}

Did I do something wrong?

Is my scenario expected?

Thank you.
