How can I specify a BOM in a multiplatform project?

kotlin {
    jvm()
    android()

    sourceSets {
        val androidMain by getting {
            dependencies {
                implementation(platform(libs.androidx.compose.bom)) // Unresolved reference: platform
                implementation(libs.androidx.compose.material3)
            }
        }
    }
}

[ephemient]

either don't use version catalog or switch to the top-level dependencies block

[ephemient]

e.g.

dependencies {
    "androidMainImplementation"(platform(...))
}

[CLOVIS]

I just migrated to the version catalogs 😅

[CLOVIS]

I'll use the top-level for just that dependency then, and migrate it when it's fixed

[Adam S]

could you try this?

implementation(project.dependencies.platform(libs.androidx.compose.bom))

[CLOVIS]

@Adam S it compiles

[CLOVIS]

I get e: java.lang.Error: Something went wrong while checking for version compatibility between the Compose Compiler and the Kotlin Compiler. It is possible that the versions are incompatible. though (did not touch the versions)

[ephemient]

you can check what it resolved to but I don't think that works currently. ideally it should, though

[CLOVIS]

How can I check?

[CLOVIS]

I get the same message with the top-level dependencies block

[ephemient]

./gradlew dependencies --configuration androidMainCompileClasspath

and see if the bom constraints appear

[CLOVIS]

Configuration 'androidMainCompileClasspath' not found in configuration container. 🤔

[CLOVIS]

Ah, I'm on Kotlin 1.7.20 and that was renamed in 1.8.0, right?

[ephemient]

oh. then try a top-level

dependencies {
    implementation(platform(...))

[CLOVIS]

I'll be migrating to Kotlin 1.8.0 in the coming week or so

[ephemient]

well that looks like a bom applied

[CLOVIS]

Should I just ignore the compatibility warning then? (how?)

[ephemient]

oh now that I check the message you posted

[ephemient]

that has nothing to do with the bom

[Adam S]

do you know which version of the 'Compose Compiler' your project has? I can't see it under the compile classpath, but maybe I've missed it. According to this https://developer.android.com/jetpack/androidx/releases/compose-kotlin it should be 1.3.2 (since you're using Kotlin 1.7.20), but possibly the warning is being triggered before the version has been resolved...?

[CLOVIS]

I have the compose-jb plugin 1.2.1, if that helps
