How can a Kotlin/JS gradle subproject depend on a ...

How can a Kotlin/JS gradle subproject depend on a Kotlin/Multiplatform subproject ? In my case I have the following gradle project structure:

client/               <= Kotlin/JS subproject
 |- build.gradle.kts  <= What should I put here to allow client to depend on :shared ?
server/               <= Kotlin/JVM subproject
 |- build.gradle.kts  <= What should I put here to allow server to depend on :shared ?
shared/               <= Kotlin/Multiplatform subproject
 |- build.gradle.kts

I tried to put this but it didn't work:

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

What do you mean by “it didn’t work”?

[jdemeulenaere]

It fails with

Could not determine the dependencies of task ':client:packageJson'.
> project ':shared' is not configured for JS usage

[egorand]

Does the dependency work in the server project? I.e. is it a JS-only issue?

[jdemeulenaere]

Yes, it does work with the server project (I didn't actually try because it was not working with JS, so thanks for the question 🙂 )

See if you can work around it by publishing the multiplatform module to Maven Local and consuming it from there, instead of having a project() dependency - this might work. If not, I’d file a Youtrack issue.

[egorand]

Also, since publishing multiplatform projects requires Gradle metadata support, make sure you’re either on Gradle 6.x or have enableFeaturePreview("GRADLE_METADATA") in your settings.gradle.

The error sounds like you're missing a js target in your shared module

kotlin {
  ...
  js {
    browser() // and/or nodejs()
  }
}

[jdemeulenaere]

Indeed, adding this made the trick! I had the js {} block but not the browser() line. Thanks 🙂

[egorand]

Good catch! Perhaps the error message could be better.
