> CDC though Kafka uses {{KafkaConsumer}} and {{KafkaProducer}}, which are parts of  {{kafka-clients}} module. 
> But when you build ignite-cdc-ext with a below command:
> {code}
> mvn clean package -f modules/cdc-ext/ -P checkstyle,extension-release -DskipTests
> {code}
> you will obtain zip file with a structure  [^ignite-cdc-ext-current.txt], where {{kafka-clients}} dependency _*is missing*_.
> So, when you try to start {{KafkaToIgniteCdcStreamer}} or {{IgniteToKafkaCdcStreamer}} you will obtain missing classes error.
> Building of module changed after IGNITE-16847, IGNITE-16815. Structure was:  [^ignite-cdc-ext-old.txt]. As you can see, there was many jar libraries included, but i'm not sure whether all of them needed to run CDC.
> I have prepared a patch [^cdc-ext-build-patch.patch], which replaces _kafka_2.12-2.7.0.jar_ by _kafka-clients-2.7.0.jar_ and tested it locally: problems with missed classes eliminated and it seems, that simple active-active replication cases works fine. But, patch does not fix other dependencies from old build assembly structure (I'm not sure, that all dependencies satisfied). 
> Structure after patch:   [^ignite-cdc-ext-patch.txt] 
> Also, proposed patch affects other modules, which uses {{/assembly/bin-component-shared.xml}} in build process.
