I might have missed it but couldn't find this asked before......is there example of how to use different versions of Kotlin in a multi-module KMP project? I can do something like following perhaps but in this case I need to use different versions of multiplatform one in different modules

resolutionStrategy {
    eachPlugin {
        if (requested.id.id == "org.jetbrains.kotlin.android") {
            useModule("org.jetbrains.kotlin:kotlin-gradle-plugin:1.9.20-Beta2")
        }
        if (requested.id.id == "org.jetbrains.kotlin.multiplatform") {
            useModule("org.jetbrains.kotlin:kotlin-gradle-plugin:1.9.10")
        }
    }
}

That sounds risky as 2 different KPG versions will clash if they ever end up in the same classloader

[mbonnin]

But why not use 1.9.20-Beta2 everywhere?

I have a Wasm based Compose for Web module that right now will only work with older version of Kotlin

[mbonnin]

You could try loading different KGP versions in different submodules (instead of loading a single version in buildSrc /`root/build.gradle.kts` ) but TBH this sounds like it'll add more issue than it will solve

[John O'Reilly]

Also this will probably only work while the wasm module isn't using shared kmp code given both of them are using kotlin("multiplatform") plugin

[John O'Reilly]

(assuming main shared module is using later version)

[John O'Reilly]

can use following approach for iOS client....unless something sort of similar could be done in this case based on which client/module is being built/run https://johnoreilly.dev/posts/kmm-using-different-kotlin-versions/
