Alpakka kafka consumer

Play Framework
,
1

Hello,
I am using following code to create a plainsource consumer:

Config consumerConfig = config.getConfig("discovery-consumer");
log.info("creating plainsource consumer {} ", consumerConfig); 
ConsumerSettings<String, String> settings = ConsumerSettings.create(consumerConfig, new StringDeserializer(), new StringDeserializer())
             .withEnrichCompletionStage(DiscoverySupport.consumerBootstrapServers(config,getContext().getSystem()))
             .withGroupId(kafkaConfig.GroupID)
             .withProperty(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "earliest")
             .withStopTimeout(Duration.ofSeconds(5));

and here is the config:

akka.kafka.consumer {
    max-retries = 5
    check-interval=5000ms
    stop-timeout = 1000ms
    discovery-method = config
    service-name = "ec2Kafka"

  connection-checker {
   enable = false
    max-retries = 3
    check-interval = 15s
    backoff-factor = 2.0
  }
}

discovery-consumer: ${akka.kafka.consumer} {
  service-name = "ec2Kafka"
  resolve-timeout = 100 ms
}

ec2Kafka = {
    endpoints = [
      { host = "xxx.xxx.xxx.xxx", port = 9092 }
    ]
}

The code works perfectly in sample java main project. But when integrated with play 2.8.8, i get following warning:
<K,V>consumerBootstrapServers(com.typesafe.config.Config,akka.actor.ActorSystem) in akka.kafka.javadsl.DiscoverySupport has been deprecated

and in Play it throws error while creating the consumer.

Dependencies:

val AkkaVersion = "2.6.15";
val AlpakkaVersion = "2.0.1" ;
val AlpakkaKafkaVersion = "2.0.5" ;
......
    "com.lightbend.akka" %% "akka-stream-alpakka-elasticsearch" % AlpakkaVersion,
    "com.typesafe.akka" %% "akka-stream-kafka" % AlpakkaKafkaVersion,
    "com.typesafe.akka" %% "akka-discovery" % AkkaVersion,
    "com.typesafe.akka" %% "akka-stream" % AkkaVersion,
    "com.typesafe.akka" %% "akka-actor-typed" % AkkaVersion,
    "com.typesafe.akka" %% "akka-actor" % AkkaVersion,

My question:

  1. the same code and conf works in java main application without warnings and able to see the consumed messages.
  2. it does not work in play framework - addSbtPlugin(“com.typesafe.play” % “sbt-plugin” % “2.8.8”).

sbt version 1.5.2

Breaking my head for the past two days. Can someone throw some light ?

Thanks and Regards
