I'm trying to set up a project with two data sources, one is MongoDB and the other is Postgres. I have repositories for each data source in different packages and I annotated my main class as follows:

@Import(MongoDBConfiguration.class, PostgresDBConfiguration.class)
@SpringBootApplication(exclude = 
 MongoRepositoriesAutoConfiguration.class,
 JpaRepositoriesAutoConfiguration.class
)
public class TemporaryRunner implements CommandLineRunner 
...

MongoDBConfiguration:

@Configuration
@EnableMongoRepositories(basePackages = 
 "com.example.datastore.mongo",
 "com.atlassian.connect.spring")
public class MongoDBConfiguration 
...

PostgresDBConfiguration:

@Configuration
@EnableJpaRepositories(basePackages = 
 "com.example.datastore.postgres"
)
public class PostgresDBConfiguration 
...

And even though I specified the base packages as described in documentation, I still get those messages in the console:

13:10:44.238 [main] [] INFO o.s.d.r.c.RepositoryConfigurationDelegate - Multiple Spring Data modules found, entering strict repository configuration mode!
13:10:44.266 [main] [] INFO o.s.d.r.c.RepositoryConfigurationExtensionSupport - Spring Data MongoDB - Could not safely identify store assignment for repository candidate interface com.atlassian.connect.spring.AtlassianHostRepository.

I managed to solve this issue for all my repositories by using MongoRepository and JpaRepository but AtlassianHostRepository comes from an external lib and it is a regular CrudRepository (which totally makes sense because the consumer of the lib can decide what type of DB he would like to use). Anyway it looks that basePackages I specified are completely ignored and not used in any way, even though I specified com.atlassian.connect.spring package only in @EnableMongoRepositories Spring Data somehow can't figure out which data module should be used.
Am I doing something wrong? Is there any other way I could tell spring data to use mongo for AtlassianHostRepository without changing the AtlassianHostRepository.class itself?

The only working solution I found was to let spring data ignore AtlassianHostRepository (because it couldn't figure out which data source to use) then create a separate configuration for it, and simply create it by hand:

@Configuration
@Import(MongoDBConfiguration.class)
public class AtlassianHostRepositoryConfiguration 

 private final MongoTemplate mongoTemplate;

 @Autowired
 public AtlassianHostRepositoryConfiguration(final MongoTemplate mongoTemplate) 
 this.mongoTemplate = mongoTemplate;
 

 @Bean
 public AtlassianHostRepository atlassianHostRepository() 
 RepositoryFactorySupport factory = new MongoRepositoryFactory(mongoTemplate);
 return factory.getRepository(AtlassianHostRepository.class);
 

This solution works fine for a small or limited number of repositories used from a library, it would be rather cumbersome to create all the repositories by hand when there are more of them, but after reading the source code of spring-data I see no way to make it work with basePackages as stated in documentation (I may be wrong though).
