How can I specify a BOM in a multiplatform project?
Copy code
kotlin {
    jvm()
    android()

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

either don't use version catalog or switch to the top-level dependencies block
e.g.
Copy code
dependencies {
    "androidMainImplementation"(platform(...))
}

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

could you try this?
Copy code
implementation(project.dependencies.platform(libs.androidx.compose.bom))
c

@Adam S it compiles
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)

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

How can I check?
I get the same message with the top-level dependencies block

Copy code
./gradlew dependencies --configuration androidMainCompileClasspath
and see if the bom constraints appear

Configuration 'androidMainCompileClasspath' not found in configuration container.
🤔
Ah, I'm on Kotlin 1.7.20 and that was renamed in 1.8.0, right?

oh. then try a top-level
Copy code
dependencies {
    implementation(platform(...))

well that looks like a bom applied

CLOVIS

03/18/2023, 1:43 PM
Should I just ignore the compatibility warning then? (how?)
e

ephemient

03/18/2023, 1:44 PM
oh now that I check the message you posted
that has nothing to do with the bom

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...?

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