Hi,
Whenever adding spring-kafka-test as a dependency I cannot run tests.
Tests start to fail for following reason:

org.gradle.api.internal.tasks.testing.TestSuiteExecutionException: Could not complete execution for Gradle Test Executor 1.
	at org.gradle.api.internal.tasks.testing.SuiteTestClassProcessor.stop(SuiteTestClassProcessor.java:64)
	...

This is what my gradle looks like:

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile
import org.springframework.boot.gradle.tasks.bundling.BootJar

    kotlin("plugin.spring") version "1.7.22"
    `maven-publish`
    `java-test-fixtures`
}

group = "com.example"
version = "0.0.1-SNAPSHOT"
java.sourceCompatibility = JavaVersion.VERSION_17

repositories {
    mavenCentral()
}

dependencies {
    api("org.jetbrains.kotlin:kotlin-reflect")
    api("org.jetbrains.kotlin:kotlin-stdlib-jdk8")

    testFixturesApi("org.springframework.security:spring-security-test")
    testFixturesApi("org.springframework.kafka:spring-kafka-test")
}

publishing {
    publications {
        create<MavenPublication>("maven") {
            groupId = project.group.toString()
            artifactId = project.name
            version = project.version.toString()

            from(components["java"])
        }
    }
}

tasks.getByName<BootJar>("bootJar") {
    enabled = false
}

tasks.getByName<Jar>("jar") {
    enabled = true
}

tasks.withType<KotlinCompile> {
    kotlinOptions {
        freeCompilerArgs = listOf("-Xjsr305=strict")
        jvmTarget = "17"
    }
}

tasks.withType<Test> {
    useJUnitPlatform()
}

Has anybody experienced similar issue?

Yes, this is a bug in spring-kafka-test version 3.0.0 which will be fixed in 3.0.1, see: https://github.com/spring-projects/spring-kafka/issues/2490

Version 3.0.1 is not released yet, so for now, you can mitigate this by manually adding a test dependency on org.junit.platform:junit-platform-launcher in your Gradle file
