After upgrading to Kotlin 1.9.20 I noticed it is no longer possible to have

commonMain

depend on source sets. I have a task that generates Kotlin files in a secondary source set which is compiled as common Kotlin. Prior to 1.9.20 that worked like https://github.com/openrndr/openrndr/blob/master/openrndr-filter/build.gradle.kts but I have no idea how to set this up in 1.9.20.

Add your generated directory to the

commonMain

source set:

kotlin.sourceSets.getByName("commonMain").kotlin.srcDir("path/to/generated/dir")

ok, so the entire idea of having the generated code in a separate sourceset should be abandoned?

Looks like it

this works for me, thanks @mbonnin
