Environment

Steps to reproduce

1. Create a new and empty Spring 3.0.0 project
2. Run tests (will work fine)
3. Add the spring-kafka-test dependency
4. Run tests again

This is out of Spring Boot's control and occurs without any involvement from Spring Boot. For example:

plugins {
	id 'java'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '17'

repositories {
	mavenCentral()
}

dependencies {
	testImplementation 'org.junit.jupiter:junit-jupiter:5.9.0'
	testImplementation 'org.springframework.kafka:spring-kafka-test:3.0.0'
}

tasks.named('test') {
	useJUnitPlatform()
}

package com.example.gh33362;

import org.junit.jupiter.api.Test;

class Gh33362ApplicationTests {

	@Test
	void contextLoads() {
	}

}

This fails in the same way. Please report the problem to the Spring Kafka team.

Thank you @wilkinsona . Just reported to the Spring Kafka team.

[wilkinsona]

Thanks, @wilsonrf.

For anyone who wants to follow along, spring-projects/spring-kafka#2490 is the Spring Kafka issue.

[garyrussell]

The new global embedded broker feature added a hard dependency for the platform launcher.

As a work around, please use

dependencies {
	testImplementation("org.junit.jupiter:junit-jupiter:5.9.1")
	testImplementation("org.junit.platform:junit-platform-launcher:1.9.1")
	testImplementation("org.springframework.kafka:spring-kafka-test:3.0.0")
}

With the non-boot version. With boot, you don’t need the version.
