I’m trying to migrate from gradle `buildscript` , ...

# gradle

I’m trying to migrate from gradle buildscript , classpath , allProjects etc. to pluginManagement , plugins , dependencyResolutionManagement etc. However errors like this happen on sync:

Error resolving plugin [id: 'org.jetbrains.kotlin.multiplatform', version: '1.8.10', apply: false]
> The request for this plugin could not be satisfied because the plugin is already on the classpath with an unknown version, so compatibility cannot be checked.

I suspect that this might be connected to the fact that I’m also using convention-plugins in buildSrc and therefore add several gradle plugins as dependencies in build.gradle.kts of buildSrc like this (but I’m not sure how to rewrite it):

plugins {
    `kotlin-dsl`
}

repositories {
    google()
    mavenCentral()
    mavenLocal()
    maven(url = "<https://maven.pkg.jetbrains.space/public/p/compose/dev>")
}

dependencies {
    implementation(Deps.Kotlin.gradlePlugin)
    // ...
}

How can this be fixed?

Where do you actually have id("org.jetbrains.kotlin.multiplatform") version "1.8.10" apply false?

In root build.gradle.kts plugins block

[Adam S]

here’s what I like to do: in buildSrc/build.gradle.kts add all Gradle plugins in the dependencies {} block (using the Maven GAV coordinates, not the plugin ID). Then I don’t need to add the plugin versions anywhere else, they’re defined in a single place.

This looks like what you’ve done too, so you probably just need to remove the versions:

plugins {
  kotlin("multiplatform") // no version needed - it's in buildSrc/build.gradle.kts
}

[Vampire]

Well, just remove it if you have it as implementation dependency in buildSrc anyway.
That already serves the same purpose.

[Vampire]

so you probably just need to remove the versions

No, the whole line 😉
