I recently upgraded to Kotlin 1.7.0 & Kotest 5.3.1, and I'm now getting a strange error. I don't understand why it's trying to pull in kotlinx-coroutines-bom:jar , which obviously wouldn't exist (pom only).

Could not find artifact org.jetbrains.kotlinx:kotlinx-coroutines-bom:jar:1.6.3

This probably isn't an error with Kotest, but it's the closest lead I have right now.

There seems to be a conflict between Quarkus 2.10.0.Final and Kotest. It doesn't happen with Quarkus 2.9.2.Final.

The only change I see is an upgrade from kotlinx-coroutines-bom 1.6.1 to 1.6.2:

It's fixed by excluding kotlinx-coroutines-bom from kotest. I am not sure why:

<dependency>
            <groupId>io.kotest</groupId>
            <artifactId>kotest-runner-junit5-jvm</artifactId>
            <scope>test</scope>
            <exclusions>
                <exclusion>
                    <groupId>org.jetbrains.kotlinx</groupId>
                    <artifactId>kotlinx-coroutines-bom</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

do you use kotlin/js?

[Richard Gomez]

Nope, JVM only.

[Emil Kantis]

Odd.. I know there was something broken with coroutines 1.6.2 where JS-targets didn't get built properly.. I think that might be causing it somehow since Kotest has JS targets, but not sure why it would matter in a JVM build..

[Richard Gomez]

Do you have a link to that? It could be related, but the issue seems to be the "jar" type/qualifier for kotlinx-coroutines-bom . It should be imported as a "pom".

I observed the same problem with Spring 2.7.1 and kotest 5.3.x/5.4.x: https://github.com/kotest/kotest/issues/3084

With spring 2.7.0 it works

[Emil Kantis]

How does your example fail @Mor4thii?

@Emil Kantis , did you check out the kotest branch? Main works as it is a plain spring app generated w/ spring initializr

🤦‍♂️ I looked at the build.gradle for the project. It didn't occur to me to check the published pom.xml file.

For me, with Spring 2.7.2, this issue has been resolved. The coroutines artifact is now available in v1.6.4 which resolves the issue.
