Quarkus exception Loading KafkaConsumerRebalanceListener

Having this Listener KafkaConsumerRebalanceListener class

@ApplicationScoped
@Identifier("responses")
public class KafkaPartitionListener implements KafkaConsumerRebalanceListener {

    private static final Logger logger = Logger.getLogger(KafkaPartitionListener.class);

    public Option<Integer> partition;

    @Override
    public void onPartitionsAssigned(Consumer<?, ?> consumer, Collection<TopicPartition> partitions) {
        logger.info("Topic partition collection received. Assigning partition");
        partition = List.ofAll(partitions)
            .headOption()
            .map(tp -> {
                logger.infov("Partition={0} assigned", tp.partition());
                return tp.partition();
            });
    }

}

When I add into my application.properties file

mp.messaging.incoming.responses.consumer-rebalance-listener.name=responses

And adding this dependency into another class

@Inject
KafkaPartitionListener partitionListener;

I'm having this exception when I run the service

java.lang.RuntimeException: io.quarkus.builder.BuildException: Build failure: Build failed due to errors
    [error]: Build step io.quarkus.arc.deployment.ArcProcessor#validate threw an exception: javax.enterprise.inject.spi.DeploymentException: javax.enterprise.inject.UnsatisfiedResolutionException: Unsatisfied dependency for type com.KafkaPartitionListener and qualifiers [@Default]

Any idea what's wrong?

You have to use same @Identifier("responses") near your injection point. It's because @Identifier have @Qualifier over it.
