After migration on 6.4.0 from 6.3.3 doesn't work following JS tests
JS lib (target browser) -> MPP lib (jvm { target 1.8 }, js { browser {} })

If JS lib contains test, than:

Kotlin 1.3.50

Hi, not sure this that this is kodein specific, with kotlin 1.3.50 jetbrains has released some new plugins for JS, maybe this is linked, we will have to reproduce this to be able to find a solution.

I create test project for this problem with described plugin configuration
https://github.com/turansky/kodein-or-kotlin-bug
Reproducing in progress.

Also I check latest EAP - 1.3.60-eap-16 - problem also reproduced.

not sure this that this is kodein specific

I also think that Kodein isn’t root cause, but migration from 6.3.3 to 6.4.0 reveals the problem.

Is there any package.json files in Kodein 6.4.0 projects?

This is related somwhow, we also migrate our build plugins between 6. 3 and 6.4. Now we'll have to find what...

Is there any package.json files in Kodein `6.4.0`projects?

I haven't been that much on the JS side lately. I'll need to work on this to give you a proper answer.

[turansky]

No problem with 6.4.1

[romainbsl]

😮 did you change something on your side ? because this is just a bugfix with on line of code correction...

[turansky]

No

Also I found WA for 6.4.0

[turansky]

WA for 6.4.0- add devDependencies block to custom package.json
With 6.4.1 WA not required
