NoClassDefFoundError: scala/collection/convert/AsJavaExtensions

I am creating EmbeddedKafkaCluster in Java test, but getting the following exception, but I have added the kafka_2.12 depedencies which have scala depedencies.

Java version: 11

Added the following depedencies

<!--Kafka Embedded Cluster dependencies -->
<dependency>
    <groupId>org.apache.kafka</groupId>
    <artifactId>kafka_2.12</artifactId>
    <version>${kafka.version}</version>
    <classifier>test</classifier>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.apache.kafka</groupId>
    <artifactId>kafka_2.12</artifactId>
    <version>${kafka.version}</version>
    <scope>test</scope>
</dependency>
