Hey, I receive error `duplicate target file will be created for 'build/node_modules/kotlin-compiler/lib/kotlin-stdlib-js.jar!kotlin.js' and 'build/node_modules/kotlin-compiler/lib/kotlin-jslib.jar!kotlin.js'` (step `:runDceKotlinJs'`) when trying to build my project on Ubuntu. I can build it on Windows. Kotlin version is 1.2.30. Where can be a problem?

```dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib-js:$kotlin_version"
    compile "org.jetbrains.kotlin:kotlin-test-js:$kotlin_version"
    compile "org.jetbrains.kotlinx:kotlinx-html-js:$html_version"
    compile 'org.jetbrains.kotlinx:kotlinx-coroutines-core-js:0.22.5'
    compile "org.jetbrains:kotlin-extensions:1.0.1-pre.19-kotlin-$kotlin_version"
    compile "org.jetbrains:kotlin-react:$react_version"
    compile "org.jetbrains:kotlin-react-dom:$react_version"
    compile "org.jetbrains:kotlin-react-router-dom:$react_router_dom_version"
}
```

```
apply plugin: 'kotlin2js'
apply plugin: 'kotlin-dce-js'
apply plugin: 'org.jetbrains.kotlin.frontend'
```

<@U0BMF6PDJ> Do you have any idea why this error appears?

Is DCE for Dead Code Elimination? Is it ok just to remove line 
`apply plugin: 'kotlin-dce-js'`?

<@U9SNRQ3CP> Yes, here is a tutorial: <https://kotlinlang.org/docs/reference/javascript-dce.html>

Thanks, I've just removed usage of this plugin. Now I am able to build project under ubuntu

I am pretty sure kotlin-frontend-plugin sets up DCE internally, so you shouldn't lose the minification when you run `bundle`

If that's not the case, ping me, I'll figure somthing out for you.

By the way, which task do you run when this happens? Does kotlin-frontend-plugin trigger that? I remember it having similar issues a few months ago, maybe it wasn't fixed for all cases.
