If it would not work at all, it would complain about

org.testcontainers:kafka

, not

org.testcontainers:junit-jupiter

. And if I try your setup, all dependencies resolve properly but

org.testcontainers:junit-jupiter

is not included at all, so I guess you miss some details here.

oh right, sorry, I posted wrong error message. It actually complains it can't download exactly

org.testcontainers:kafka

Could not find org.testcontainers:kafka:.

Well, but then it is like I said, works perfectly fine here. Can you provide an MCVE?

Sure, here is complete `build.gradle`:

plugins {
    id "java"
}

group "org.example"
version "1.0-SNAPSHOT"

repositories {
    mavenCentral()
}

dependencies {
    implementation platform("org.testcontainers:testcontainers-bom:1.17.4")
}

java {
    toolchain.languageVersion = JavaLanguageVersion.of(18)
}

testing {
    suites {
        integrationTest(JvmTestSuite) {
            dependencies {
                implementation project
                implementation "org.testcontainers:kafka"
            }
        }
    }
}

And packaged "hello-world" project which allows to reproduce it
