I update to last version Kotlin 1.4-M2 and cant call to ':compileKotlinJs' tasks directly, Gradle module have tasks but not found in build.gradle.

//Fail Call :compileKotlinJs tasks
tasks.compileKotlinJs{
        kotlinOptions.outputFile = "${projectDir}/routes/node/index2.js"
        kotlinOptions.metaInfo = false
        kotlinOptions.moduleKind = "commonjs"
}

//Work call to :compileKotlinJs
tasks {
    "compileKotlinJs"(org.jetbrains.kotlin.gradle.tasks.Kotlin2JsCompile::class) {
        kotlinOptions.outputFile = "${projectDir}/routes/node/index2.js"
        kotlinOptions.metaInfo = false
        kotlinOptions.moduleKind = "commonjs"
    }
}

Any idea because dont work tasks.compileKotlinJs If exists in Gradle module?

There are 3 JS modes in M2 (IR, LEGACY, BOTH)

• IR - compileKotlinJsIr
• LEGACY - compileKotlinJs
• BOTH - compileKotlinJs + compileKotlinJsIr
Plugin couldn’t create task compileKotlinJs by default, that is why task isn’t available in DSL

[frank]

I tried add LEGACY but continues without found compileKotlinJs in DSL.

kotlin {
    js(LEGACY) {
        nodejs { }
        binaries.executable()
    }
}

Can I do something to add in DSL?

[Ilya Goncharov [JB]]

Yes, unfortunately since we have several modes of working, we can’t predict correctly if compileKotlinJs exists.
Maybe in major count of cases it will and we can register it speculatively. But it means that in cases of both mode it will lead to error.

@frank Do you have many Kotlin/JS subprojects in project?

[frank]

Yes, I have three subprojects but I have also tried a project without subprojects and got same result.

[frank]

@Ilya Goncharov [JB], If i need setting kotlinOptions.
Do I have to use Kotlin2JsCompile::class and KotlinCompile::class until there is a stable version?

[Ilya Goncharov [JB]]

In fact, this task is registered after you write

kotlin {
    js {
    }
}

You can use either Kotlin2JsCompile or maybe KotlinJsCompile
