Hello! 👋 I am trying to switch our medium-sized Kotlin project from using kotlintest to kotest. However, we have a grpc project, where Kotest is having some issues. Has anybody seen this? Would you have suggestions on how to fix it?

* What went wrong:
Execution failed for task ':integration-grpc-server:extractIncludeTestProto'.
> Could not resolve all files for configuration ':integration-grpc-server:testCompileProtoPath'.
   > Could not resolve io.kotest:kotest-runner-junit5-jvm:4.0.2.

        All of them match the consumer attributes:

Jvm version: Using java version 13.0.2.hs-adpt

This worked fine with the latest version of kotlintest.

[LeoColman]

I've never seen that.

[LeoColman]

My first suggestion would be to try and update your Gradle version

[LeoColman]

So we can discard maybe old gradle bugs

[sam]

If it's an old version of gradle but anything 6+ should be good

[sam]

I've never seen this jvm-api / runtime thing before

[sam]

Must be something odd in the "protopath" thing? Does grpc have it's own gradle plugin / source roots

[Attila Domokos]

Using the latest version of Gradle:

% ./gradlew --version

Gradle 6.3

Something is funky with this subproject, I did not set it up. I was hoping someone has bumped into this and could say, "hey, just set the java version" or something like that.

[sam]

yeah never seen those errors before

[sam]

I'm tempted to think it's that protoPath plugin

[Attila Domokos]

Ha, it seems others are bumping into this: https://github.com/google/protobuf-gradle-plugin/issues/391

[Attila Domokos]

I cloned this repo: https://github.com/olamelin/protobuf-gradle-plugin-issue
Just build it with ./gradlew build to replicate the issue.
I added this to the protomodule/build.gradle.kts file so it looks like this:

plugins {
	kotlin("jvm")
    id("com.google.protobuf") version "0.8.11"
}

dependencies {
    implementation(project(":okhttp"))
}

configurations.forEach {
    if (it.name.toLowerCase().contains("proto")) {
        println(it.name.toLowerCase())
        it.attributes.attribute(Usage.USAGE_ATTRIBUTE, objects.named(Usage::class.java, "java-runtime"))
    }
}

And it works!

There you go
