Hi all. I'm trying out the multi-platform feature and I am getting the following error.
Error:(3, 1) Kotlin: The feature "multi platform projects" is experimental and should be enabled explicitly.

I cannot find any documentation on where to enable multiplatform build. I tried

kotlin {
    experimental {
        multiplatform 'enable'
    }
}

but this doesn't work. Anyone run into this issue?

Take a look at docs here: https://kotlinlang.org/docs/reference/multiplatform.html
And a small favour: please post code in code blocks

Also here is a sample project: https://github.com/hhariri/kotlin-mpp-sample

If you look at the build.gradle file you'll find explicitely applied kotlin-platform-* plugins. Probably you're missing those

I looked through my build files and all plugins are using the appropriate kotlin-platform-*. I will try to do a simple sample project to see where I went wrong.

Reporting back. I have built a simple example targeting just the jvm. The plugins were not the problem. Due to how I was launching the application, via the TornadoFX plugin, I was receiving the wrong error messages. My real problem was Duplicate JVM class name 'us/nightware/kmod/DateTimeKt'. So I was creating a class DateTime at the same level in the same named file. I moved the common DateTime to a file called PlatformCommon.kt and it runs without errors.

Good to hear you fixed it 🙂
