Support for KSP2 (for beta K2 compiler exploration)

[laurentperez]

Hi

Upgrading from K1 compiler 1.9.23 to K2 id 'org.jetbrains.kotlin.jvm' version "2.0.0", a project using Kotlin dataframe id "org.jetbrains.kotlinx.dataframe" version "0.13.1" does not compile anymore

This is related to a java.lang.NoSuchMethodError in KSP when the project is upgraded from K1 to K2. This may be similar to https://youtrack.jetbrains.com/issue/KT-68732/Kotlin-Multiplatform-Gradle-Sync-Issue-Latest-Stable-of-Multiplatform-Plugin-2.0.0

Per https://github.com/google/ksp/releases users are "encouraged" to try out KSP2.

Are Kotlin dataframes expected to support K2/KSP2 ? or should I stick to a specific K1 1.x.x compiler for now ?

thanks

@Jolanrensen could you please have a look?

Hi @laurentperez! Could you try this temporary fix #649 (comment)? It will allow you to have your own KSP version independent of DataFrame's provided KSP version.
This is only temporary of course :) We're almost ready to update the library to Kotlin 2.0 too, then this won't be necessary anymore.

[Jolanrensen]

The next release (0.14.0) will be based on 2.0 so the problem should be fixed. In the meantime, you could try it with the latest dev version https://central.sonatype.com/artifact/org.jetbrains.kotlinx/dataframe?smo=true
