Hi,

I’ve got a KotlinJs project compiling, using the Gradle plugin. It seems to work but I get a warning for every single source file. This is 1.1-M04.

> :MyProject:compileKotlin2Js  
> w: Duplicate source root: /MyProject/src/main/kotlin/com/foo/Application.kt  
> w: Duplicate source root: /MyProject/src/main/kotlin/com/foo/AsyncRequests.kt  
> …

Anyone else getting this? A bug?

Rob

Did you have any luck resolving this?

I think it might be related to using gradle-subprojects.

I don’t think so. I only work on that project once every few months, so I can’t remember anything about it at the moment.

see [https://youtrack.jetbrains.com/issue/KT-15829](https://youtrack.jetbrains.com/issue/KT-15829)  
It is reproducible in almost empty gradle project. Just some minor glitch in plugin.
