Kafka testcontainer not running

Question

I am trying to setup an integration test env for debezium integration (following the instructions in this example) but the test container (default image: confluentinc/cp-kafka:5.2.1) doesn't start but throws an exception.

I am using below mentioned code to create a KafkaContainer bean

    @Bean
    public KafkaContainer kafkaContainer() {
        if (kafkaContainer == null) {
            kafkaContainer = new KafkaContainer()
                    .withNetwork(network())
                    .withExternalZookeeper("172.17.0.2:2181");

                kafkaContainer.start();
           }
        }

        return kafkaContainer;
    }

it throws following exception.


***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.testcontainers.containers.KafkaContainer.getBootstrapServers(KafkaContainer.java:91)

The following method did not exist:

    org/testcontainers/containers/KafkaContainer.getHost()Ljava/lang/String;

The method's class, org.testcontainers.containers.KafkaContainer, is available from the following locations:

    jar:file:/home/shubham/.m2/repository/org/testcontainers/kafka/1.14.3/kafka-1.14.3.jar!/org/testcontainers/containers/KafkaContainer.class

The class hierarchy was loaded from the following locations:

    org.testcontainers.containers.KafkaContainer: file:/home/shubham/.m2/repository/org/testcontainers/kafka/1.14.3/kafka-1.14.3.jar
    org.testcontainers.containers.GenericContainer: file:/home/shubham/.m2/repository/org/testcontainers/testcontainers/1.12.5/testcontainers-1.12.5.jar
    org.testcontainers.containers.FailureDetectingExternalResource: file:/home/shubham/.m2/repository/org/testcontainers/testcontainers/1.12.5/testcontainers-1.12.5.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.testcontainers.containers.KafkaContainer

More details, please? What kind of exception? Also, even though you posted a link, it's still better to add a code snippet — Vitaly Chura, Sep 09 '20 at 14:53
@VitalyChura I have added code snippets and strack trace logs. — S. Arora, Sep 09 '20 at 19:45

Used an older version of org.testcontainers in maven dependencies and it worked. Thanks!
