We are in the process of moving away from the frontend plugin to the new JS plugin. Everything works fine for a while, but then compiles in IntelliJ starts failing with the stacktrace below. The error and the warnings about invalid Kotlin Javascript libraries goes away for a while if the .idea folder is deleted and IntelliJ restarted. However, after some time it reappears.

Has anyone had a similar problem, and know of a way to solve it?

Do you use both Gradle and IntelliJ build system?

[Mranders]

Yes, I do builds in a prompt using gradle, and in the IntelliJ build system.

Your question gave me an idea to test something, based on when the error occured the last time. It seems that changing the IntelliJ setting "Build and run using" from "Gradle" to "IntelliJ IDEA" causes the error to appear.

[Ilya Goncharov [JB]]

And what do your purpose? Do you want build with intelliJ or build with Gradle is enough for you?
For now we recommend to use Gradle builds, but we can investigate problem with IntelliJ build system too.
You can test gradle build with command line ./gradlew build or run task in Gradle tool bar in IDEA

[Mranders]

I've had no problems building from the command line.

Our setup has been using non-delegated builds up until now, and e.g. our ktor hot-reload watch configuration was based on this. I was not aware that the javascript/multiplatform plugins would not work with non-delegated builds. We'll switch to delegated builds and make the necessary changes.

Thank you for the quick feedback.

Sorry if I'm thread-jacking, but is there a place that lists the differences between running with Gradle vs running with IntelliJ? Just want to make sure I understand the tradeoffs

[Ilya Goncharov [JB]]

I am mot sure about such list, but run with IntelliJ build system (so called JPS) provide basic functionality with compilation only. There is no additional tooling with integration with some JavaScript ecosystem stuff (karma, webpack for example).
