Hi everybody, does anyone know a way to change the artifactId in the kotlinMultiplatformPublication, when using kotlin multiplatform and maven-publish gradle plugin?

[mbonnin]

publishing {
  publications {
    withType<MavenPublication> {
      artifactId = "foobar"
    }
  }  
}

Something along those lines ☝️

Thinking more about this, KMP has multiple publications so you want to change the base of the artifact id so that not to overwrite all the -jvm , -macodArm64 , etc..

The easiest is probably to change the project name. IIRC, this is what's used by default

I have multi-module project, so changing module names is really confusing.

You might be able to overwrite:

publishing {
  publications {
    withType<MavenPublication> {
      artifactId = "foobar-${artifactId.substringBefore("-")}"
    }
  }  
}

And wrap in afterEvaluate{} if that's not working (not pretty but 🤷 )

I mean the snippet:

publishing {
  publications {
    withType<MavenPublication> {
      artifactId = "foobar"
    }
  }  
}

makes it only generate only one artifact, and i also need platform specific ones. but i can just use artifactId = "foobar-${artifactId.split()[1]}"

Have anyone found a good solution for this, so that we could customize the artifactId without having it defaulting to the Gradle project's name?
