The examples fail if trying to run on Kotlin Native

I'm using Android Studio on Linux with version:

I'm trying to run the examples that contain Native targets (kotest-multiplatform and kotest-native) running the Gradle task linuxX64Test.

The kotest-multiplatform example fails with:

While in the kotest-native example, the gradle sync task fails with:

e: file:///home/fri/kotest-examples-master/kotest-native/build.gradle.kts:14:1: Unresolved reference: kotest

Now, I commented out lines from 14 to 16 in build.gradle.kts, in order to
make gradle sync work, but then trying to run the test results in the
following error:

So my question is:

How do I make Kotest work on Native platforms?

[krzema12]

I recall some Maven artifacts were missing in the pre-releases. @bugnano can you check again if you're affected with kotest 6.0.0?

[bugnano]

Now, I updated the git repo with the latest commits (so everything is using kotest version 6.0.1).

Unfortunately, the kotest-multiplatform tests still fail.

On the JVM they fail with:

> Task :jvmTest FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':jvmTest'.
> No tests found for given includes: [io.kotest.examples.mpp.uuid.UUIDTestCommon](--tests filter)

> Run with --info or --debug option to get more log output.
> Run with --scan to generate a Build Scan (Powered by Develocity).
> Get more help at https://help.gradle.org.
BUILD FAILED in 2s

On native they fail with:

> Task :linkDebugTestLinuxX64 UP-TO-DATE
Error while processing test process output message "##teamcity[testFinished name='uuids should have length 15' id='UUIDNativeTest/uuids should have length 15' parent_id='UUIDNativeTest' duration='0' result_status='Success']

oh, and btw. there are no options for testing on Android in the kotest-multiplatform example (which for my use case is a huge issue, considering that I'd like to use kotest in a multiplatform app that targets both Android and iOS).

The kotest-native example fails with:

Error running 'CoroutinesTest (1)'
io.kotest.launcher.TeamCityMessages PluginClassLoader(plugin=PluginDescriptor(name=kotest, id=kotest-plugin-intellij, descriptorPath=plugin.xml, path=~/.local/share/Google/AndroidStudio2025.1.1/kotest-intellij-plugin, version=6.0.101-2025.1, package=null, isBundled=false), packagePrefix=null, state=active, parents=PluginDescriptor(name=Kotlin, id=org.jetbrains.kotlin, moduleName=kotlin.features-trainer, descriptorPath=kotlin.features-trainer.xml, path=/snap/android-studio/197/plugins/Kotlin, version=251.25410.109.2511.13665796-AS, package=org.jetbrains.kotlin.training, isBundled=true), PluginDescriptor(name=Kotlin, id=org.jetbrains.kotlin, moduleName=kotlin.project-wizard.maven, descriptorPath=kotlin.project-wizard.maven.xml, path=/snap/android-studio/197/plugins/Kotlin, version=251.254

So unfortunately no, nothing has been fixed yet.
