I have a multiplatform project with kotlin js and I need to use kotlin 1.3.31. Right now intellij idea creates a configuration which uses kotlin 1.3.40 and some stuff which are not available before this version. I am talking about these: 1)

kotlin{
  ...
   js {
    browser {
    }
  }
}

2)

jvmBackendJar {
    dependsOn(jsBrowserWebpack)
    from(new File(jsBrowserWebpack.entry.name, jsBrowserWebpack.outputPath))
}

how can I replicate these tasks without kotlin 1.3.40? Can someone share an older mpp config with js? Thanks 🙂

Running webpack was not supported in the Kotlin Gradle plugin in any way before 1.3.40. However, we had a separate

kotlin-frontend

plugin that could run webpack. You can try it: https://github.com/Kotlin/kotlin-frontend-plugin

I tried applying the plugin and got some issue:

apply plugin: 'org.jetbrains.kotlin.frontend'

apply plugin: 'kotlin2js'

And got the error

Cannot add extension with name 'kotlin', as there is an extension already registered with that name.

So i removed the kotlin2js plugin and got this issue:

The 'java' plugin has been applied, but it is not compatible with the Android plugins.

Removing both let me compile the project without any issue
