Is it currently possible to use KSP to process common code? There is no configuration for kspCommonMain , and doing add("kspCommonMainMetadata",...) does not cause a `kspCommonMain`/metadata task to execute on build of one of the platforms. I don't see any such task being generated either.

[Fudge]

Okay, if you only have one platform the task won't exist

[Fudge]

Doesn't run though

[mbonnin]

What do you mean by “doesn’t run”?

[mbonnin]

you should have a kspCommonMainKotlinMetadata task

[mbonnin]

We’re doing it successfully here

[mbonnin]

(Anecdotally, I got hit yesterday with a problem when there is a single jvm platform but I don’t think it’s the same problem here)

[eygraber]

I have a generalized function for handling that https://github.com/eygraber/gradle-conventions/blob/master/conventions-plugin/src/main/kotlin/ksp.kt#L32

[mbonnin]

The IDE completion is still not working right?

[mbonnin]

(I’m doing something similar but can’t get IntelliJ to recognize my symbols)

[eygraber]

Completion for which part? I haven't paid attention to it in a while, but everything used to work as expected.

[mbonnin]

The symbols in build/generated/ksp/metadata/commonMain/ . They’re somehow all red for me

[eygraber]

I think that's what https://github.com/eygraber/gradle-conventions/blob/master/conventions-plugin/src/main/kotlin/ksp.kt#L45 addresses. It's worked for me in the past.

[mbonnin]

I have it too here but somehow not working, maybe there’s an order issue or something. I’ll try again with KSP2

[eygraber]

Maybe it's something to do with the difference between lazy (named(...).configure) vs eager (findByName). I think someone once told me there's no difference between those for source sets, but you never know.

@mbonnin my original issue was that I only had JVM

[arnaud.giuliani]

Hello there 👋 I have the same problem: having kspCommonMainMetadata task in my project, but no target is triggering it (neither android, nor iOS ...). Do we need to ask to special setup then?

[mbonnin]

See the code for Eliezer above: https://github.com/eygraber/gradle-conventions/blob/master/conventions-plugin/src/main/kotlin/ksp.kt#L32

[mbonnin]

You’ll need to set the dependency manually:

project.tasks.withType(KotlinCompilationTask::class.java).configureEach {
    if(name != "kspCommonMainKotlinMetadata") {
      dependsOn("kspCommonMainKotlinMetadata")
    }
  }

[arnaud.giuliani]

arf ok. Need to be part of the documentation to help people setup my lib 👍

[arnaud.giuliani]

Thanks @mbonnin wasn't sure if it was that

[mbonnin]

@arnaud.giuliani another option is to ship a Gradle plugin that does the wiring automagically, saves a bit of boilerplate to your users
