Support kafka client 3.4.1 in spring-kafka-test

[tomlicha]

Hi,

I've recently bumped into an issue trying to upgrade to kafka client 3.4.1 with spring boot 3.1.1, it appears that the spring-kafka-test dependency still uses kafka-client 3.3.2. Is there an upgrade already scheduled ?

Spring versioning rules do not allow us to change minor versions of dependencies in a patch release.

The documentation shows how to override the dependency (3.5.1 is now available).

See https://docs.spring.io/spring-kafka/docs/current/reference/html/#update-deps

When upgrading one version, you must upgrade them all; when you use Boot's dependency management, that will happen automatically, because Boot uses spring-kafka-bom.

Hi, I have upgraded to 3.5.1, but in EmbeddedKafkaBroker they still call test utils from kafka_2.13:3.3.2, is there a workaround ? I cannot just exclude 3.3.2 because otherwise, test utils is no more defined

See

https://docs.spring.io/spring-boot/docs/current/reference/html/using.html#using.build-systems.dependency-management

and

https://docs.spring.io/spring-boot/docs/3.1.3/maven-plugin/reference/htmlsingle/

about using dependency management.

It makes it much easier to override versions, as we show here:

https://docs.spring.io/spring-kafka/docs/current/reference/html/#update-deps

appologies, I've sent you the parent pom, here is what i am using at the test level :

        <dependency>
            <groupId>org.apache.kafka</groupId>
            <artifactId>kafka_2.13</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.kafka</groupId>
            <artifactId>spring-kafka</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.kafka</groupId>
            <artifactId>spring-kafka-test</artifactId>
            <scope>test</scope>
        </dependency>

Please learn GitHub markdown (see after my edit).

This is the pom from my smoke test, that overrides the kafka.version in a Boot 3.0.10/3.1.3 project...
