Unresolved reference: compileKotlin2Js in Intellij Idea 2018.3

[pankajbsn]

In Intellij Idea 2018.3 when I create a new KotlinJS gradle project, with kotlin-dsl, In build.gradle.kts it gives me error that "Unresolved reference: compileKotlin2Js". However, when I import hello-js sample project in same IDE, it works fine. I cant figure out what is the difference. I am using the same build.gradle.js as from hello-js sample project.

Changing gradle version from 4.10.2 to 5.0 resolved the issue. After that from command line it worked but Intellij Idea was still giving error. In IDE --> Settings --> Gradle --> Use Local Gradle distribution. And then I set Gradle 5 as home. Then it stopped giving error in IDE as well. Although, I don't understand, why it was not working with Gradle 4.10.2.

It seems Kotlin plugin in IDEA 2018.3 is broken, upgrade gradle to 5.0 worked for me

For those who cannot upgrade to Gradle 5.x (e.g. due to a bug in the kotlin-frontend-plugin: https://github.com/Kotlin/kotlin-frontend-plugin/issues/122). There is a workaround for Gradle 4.10.3:

tasks {
    "compileKotlin2Js"(Kotlin2JsCompile::class) {
        kotlinOptions {
            outputFile = ...
            sourceMap = true
        }
    }
}
