Is there a dev build of the Jetbrains compiler that can be used with Kotlin 2.0.0-Beta1 or should I use the Jetpack compiler?

What maven repo does that come from?

Don’t know exactly, but try one of these: https://github.com/OliverO2/compose-counting-grid/blob/master/settings.gradle.kts

Found it, it's https://maven.pkg.jetbrains.space/public/p/compose/dev. Thanks!
