Kafka Getting error No resolvable bootstrap urls given in bootstrap servers

I'm pretty sure the bootstrap.servers is correct. Is there anything confliction in Maven or what wrong with Kafka??

Before that It was working successfully. I added some Maven or Spark then something went wrong..

Can anyone knows how to resolve it?

Here is kafka code in java

Properties props = new Properties();
        props.put("bootstrap.servers", "x.xx.xxx.xxx:9092");
        props.put("metadata.broker.list", "x.xx.xxx.xxx:9091, x.xx.xxx.xxx:9092, x.xx.xxx.xxx:9093");

        props.put("producer.type", "async");
        props.put("batch.size", "500");
        props.put("compression.codec", "1");
        props.put("compression.topic", topicName);
        props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
        props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");

            org.apache.kafka.clients.producer.Producer<String, String> producer = new KafkaProducer<String, String>(
                    props);

Getting error No resolvable bootstrap urls given in bootstrap servers,

"metadata.broker.list" is deprecated and "bootstrap.servers" is used instead. Removing "metadata.broker.list" configuration from your code should resolve the problem. Please find more details at difference between bootstrap.servers and metadata.broker.list
