Dependency management for Apache Kafka is incomplete #29023
Description
The current Apache Kafka management is like this:
library("Kafka", "3.0.0") { group("org.apache.kafka") { modules = [ "connect-api", "connect-basic-auth-extension", "connect-file", "connect-json", "connect-runtime", "connect-transforms", "kafka-clients", "kafka-metadata", "kafka-log4j-appender", "kafka-streams", "kafka-streams-scala_2.12", "kafka-streams-scala_2.13", "kafka-streams-test-utils", "kafka-tools", "kafka_2.12", "kafka_2.13" ] } } There are two more dependencies which would really use for testing in Spring for Apache Kafka when our @EmbeddedKafka is involved:
<dependency> <groupId>org.apache.kafka</groupId> <artifactId>kafka-clients</artifactId> <classifier>test</classifier> <scope>test</scope> <version>${kafka.version}</version> </dependency> <dependency> <groupId>org.apache.kafka</groupId> <artifactId>kafka_2.13</artifactId> <classifier>test</classifier> <scope>test</scope> <version>${kafka.version}</version> </dependency> Pay attention to that <classifier>test</classifier>.
They come as transitive dependencies from spring-kafka-test but if we need to override an Apache Kafka version for some reason, we also have to add those two dependencies explicitly: https://docs.spring.io/spring-kafka/docs/2.8.1-SNAPSHOT/reference/html/#update-deps.
It probably would be much nicer just be let end-users to specify a Kafka version like ext['kafka.version'] = '2.8.1' and everything else comes to us from Spring Boot management.
Thanks
P.S. I would PR the fix, but I don't know how specify a test classifier in Gradle configuration 😄
