spring cloud stream and gcp pub sub, binder problem

I'm tryng to run an SCS app locally using GCP's Pub Sum as binder. K m mmkkkk. Mmm org.sm.Mpringframework.cloudkki spring-cloud-gcp-starter-pubsub M Here is the configl

@Configu@Configukration
@EnableBindingkklk(Source.class)
public class TimerSourcek {

  @Bean
  @InboundChannelAdapter(channel = "channel", poller = @Poller(fixedDelay = "1000", maxMessagesPerPoll = "1"))
  public MessageSource<String> timerMessageSource() {
    return () -> new GenericMessage<>(new SimpleDateFormat("HH:mm:ss").format(new Date()));
  }
}

Here is the error message when starting the main app:

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2019-02-13 15:42:48.627 ERROR 22276 --- [           main] o.s.boot.SpringApplication               : Application run failed

org.springframework.context.ApplicationContextException: Failed to start bean 'outputBindingLifecycle'; nested exception is java.lang.IllegalArgumentException: A default binder has been requested, but there is no binder available

I'd like to run this code either locally or against my GCP project. How can that be done?

The spring-cloud-gcp-starter-pubsub doesn't bring for you a binder dependency. You need to use a spring-cloud-gcp-pubsub-stream-binder also:

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-gcp-starter-pubsub</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-gcp-pubsub-stream-binder</artifactId>
    </dependency>

See samples in the project for more info: https://github.com/spring-cloud/spring-cloud-gcp/tree/master/spring-cloud-gcp-samples
