no instance initialze the class io.eventuate.sync.EventuateAggregateStore

[illman2016]

There is no spring initialze bean the class of EventuateAggregateStore in mudual project path : 👎 ftgo-accounting-service/src/main/java/net/chrisrichardson/ftgo/accountingservice/domain/AccountServiceConfiguration.java , how does it works for the code below ? :
@bean
public AggregateRepository<Account, AccountCommand> accountRepositorySync(EventuateAggregateStore aggregateStore) {
return new AggregateRepository<>(Account.class, aggregateStore);
}

I can't find any spring autoConfiguration Injection bean or config class to initialze the implement of EventuateAggregateStore,
beacouse it important for class AggregateRepository instance, it depence on the new EventuateAggregateStore instance
Christ, can you answer my confuse ?
