x - posting here because I think it is relevant.

Is any one here using gradle composite build as dependency substitutors for kotlin multiplatform projects with success? Any workaround is welcomed

[Sam]

It came up a bit in this thread and I think a couple of workarounds may have been mentioned in the linked tickets

[mbonnin]

Are you concerned about Gradle build or IDE support?

[mbonnin]

We have a MPP composite build that's working well there

[andylamax]

I would love both (IDE and Gradle) to be honest. but I'll take what I can get

[mbonnin]

IDE supports is hit&miss but Gradle works fine in my experience (even if it's not 100% supported apparently). Do you have a specific error when building?

[andylamax]

@mbonnin I am getting resolution errors

> Task :authenticator-core:compileCommonMainKotlinMetadata FAILED
e: /media/andylamax/Auxilliary/Workspace/PiCortex/home/authenticator/core/src/commonMain/kotlin/authenticator/ProfileServiceCore.kt: (3, 17): Unresolved reference: RequestBody
. . .

Funny thing is the following tasks all do compile successfully
• compileKotlinMetadata
• compileKotlinJvm
• compileKotlinJs

[mbonnin]

I've seen this one. I'm on mobile right now but if you search "compileCommonMainMetadata" on this slack you should find something

[mbonnin]

Tldr: you can disable the task and you'll be fine

[andylamax]

ooooh, let me try that approach then

[andylamax]

@mbonnin, thanks a lot. Just disabling that task, seemed to work. Next, how do I get IDEA to play well now? Any hints/clues?

[mbonnin]

That's a lot more complicated story....

[mbonnin]

If you looking at https://github.com/apollographql/apollo-kotlin/tree/main/tests we do some hacks based on "idea.sync" property to use different versions of Kotlin

[mbonnin]

It's working but quite a hack

[andylamax]

I'l take what I can get

[mbonnin]

Look for constructs like

System.getProperty("idea.sync.active") == null

[mbonnin]

The idea is to use 1.6.10 during IDEA sync and a newer version at build time

[andylamax]

Its a big repo. How do I make idea use kotlin 1.6.10 after checking ?

System.getProperty("idea.sync.active") == null

do I apply a different kotlin plugin?

[mbonnin]

Yea mostly

[mbonnin]

We do it there: https://github.com/apollographql/apollo-kotlin/blob/d1ebde581e7a2c31116f4b435e847b6e1124d5c0/build-logic/build.gradle.kts#L31

[mbonnin]

But as you said, there's a lot of details. Especially, if you're using AGP you might have issues no matter what

[andylamax]

Good new is I am not using AGP

[andylamax]

I currently have it like this

plugins {
    if (System.getProperty("idea.sync.active") == null) {
        println("Idea is not syncing")
        kotlin("multiplatform") version "1.7.0" apply false
    } else {
        println("Idea is syncing")
        kotlin("multiplatform") version "1.6.10" apply false
    }
}

Tried in IDEA and AS to no avail. I realize appollo is doing the checking in a build-logic module. Is that the rout I should take as well?? or same principles should apply?

[mbonnin]

I think it doesn't have to be in build-logic but since this is all a big hack, it's hard to tell :-/
