It seems once again Kotlin/JS is broken because of some new npm dependency.

[webpack-cli] Unable to load '@webpack-cli/serve' command

Anyone can confirm?

This seems to be a workaround for Kotlin/JS projects:

rootProject.plugins.withType<org.jetbrains.kotlin.gradle.targets.js.yarn.YarnPlugin> {
    rootProject.the<org.jetbrains.kotlin.gradle.targets.js.yarn.YarnRootExtension>().apply {
        resolution("@webpack-cli/serve", "1.5.2")
    }
}

Can confirm, started to error for me roughly 10 hours ago

Happened to me right now, the workaround helped.

@Robert Jaros Thank you for the information! I will create an issue in YT and add your workaround

shouldn't some kind of lockfile prevent such situations?

[Piotr Krzemiński]

are NPM dependencies closed/locked like in Maven Central, so that noone can change it without bumping versions? it would also prevent such cases

[Robert Jaros]

You can't do anything about this on Kotlin side, as this is a bug in the webpack-cli project.

[Robert Jaros]

We just have to continue to love the JS ecosystem 😉

[Piotr Krzemiński]

FTR, the lockfile approach to avoid such surprises is somewhat possible (not perfect, but still it's there), see https://youtrack.jetbrains.com/issue/KT-34014

@Robert Jaros Thank you for providing the work-around. How would you translate this snippet to a groovy gradle.build? Thanks in advance!

[peekandpoke]

Ok figured it out myself:

rootProject.plugins.withType(org.jetbrains.kotlin.gradle.targets.js.yarn.YarnPlugin) {
    var ext = rootProject.extensions.findByType(org.jetbrains.kotlin.gradle.targets.js.yarn.YarnRootExtension)
    ext.resolution("@webpack-cli/serve", "1.5.2")
}

[peekandpoke]

Works for the moment...

Version bump works
