It seems like the Kafka test driver is not compatible with the latest kafka-streams API. When I use the following two dependencies together.
<dependency> <groupId>org.apache.kafka</groupId> <artifactId>kafka-streams-test-utils</artifactId> <version>2.2.0</version> <scope>test</scope> </dependency> <dependency> <groupId>org.apache.kafka</groupId> <artifactId>kafka-streams</artifactId> <version>2.2.0</version> <scope>compile</scope> </dependency> I get the following compiler error: java.lang.NoSuchMethodError: org.apache.kafka.common.serialization.Serializer.serialize(Ljava/lang/String;Lorg/apache/kafka/common/header/Headers;Ljava/lang/Object;)[B at In my unit test file for this function call: testDriver.pipeInput(statusFactory.create(TopicNames.ENVELOPE_STATUS, "1000", new Status("FIN", "1000", "d200", EnvelopeState.DRAFT, new Date().getTime(), "draft", null, null))); Anyone run into this problem? Changing to version 2.0.1 or Kafka Streams makes everything work.
