Support Kotlin 1.8.21

[mgroth0]

Kotlin 1.8.21 is not present on the compatibility chart, and using this kotlin version produces a warning or error.

Thanks. We will fix it.

While you waiting, you can check the RC version of our compiler plugin.
To do this, add these lines to all your gradle modules:

compose {
    kotlinCompilerPlugin.set("org.jetbrains.compose.compiler:compiler:1.4.7-rc01")
    kotlinCompilerPluginArgs.add("suppressKotlinVersionCompatibilityCheck=1.8.21")
}

Would be great to have your release support .22 as well since it's such an exceedingly minor bump (with no impact on a compiler plugins).

JB Compose compiler 1.4.7 out yesterday supports 1.8.21 but does NOT support 1.8.22 😬.

Yeah, we are waiting for Google JetPack Compose compiler with support for 1.8.22 for now

[JakeWharton]

It's out today as 1.4.8. Would be amazing to get a fast-follow from you all so we can all be up-to-date before 1.9.

@eymar Do we plan to publish new Compose compiler with Kotlin 1.8.22 before next release of Compose Multiplatform?

It was not planned. Anyway, here it is: https://maven.pkg.jetbrains.space/public/p/compose/dev/org/jetbrains/compose/compiler/compiler/1.4.8/

it requires:

compose {
    kotlinCompilerPlugin.set("1.4.8")
}

kotlin 1.8.21 is currently supported with:

compose {
    kotlinCompilerPlugin.set("1.4.7")
}

We'll update the compatibility table when those versions are supported out of a box (w/o manual configuration)

closing this issue.

[JakeWharton]

Thanks! Will that get synchronized to Maven Central so we can rely on it in places other than Compose UI multiplatform?

[eymar]

Yes, 1.4.8 should be available in MavenCentral later today (rather soon, in ~1h)
