👋 Compose beta09 thinks that my project is using kotlin 1.4.31 instead of 1.5.10. I suspect that this is because some dependencies are pulling in stdlib 1.4.31. Explicitly adding stdlib 1.5.10 as a dependency fixes this error. Is there a better way of solving this?

error: this version (1.0.0-beta09) of the Compose Compiler requires Kotlin version 1.5.10 but you appear to be using Kotlin version 1.4.31 which is not known to be compatible.  Please fix your configuration (or `suppressKotlinVersionCompatibilityCheck` but don't say I didn't warn you!).

I’ve already tried declaring kotlinCompilerVersion and kotlinCompilerExtensionVersion under composeOptions.

kotlin-bom is always nice, but without knowing the details of your dependencies it's hard to say if it'll help

TIL of kotlin-bom. Let me try using this!

[ephemient]

dependencies {
    implementation(platform(kotlin("bom"))) // kotlin dsl
    implementation platform("org.jetbrains.kotlin:kotlin-bom:$kotlin_version") // groovy dsl
}

(or something like that, I haven't used groovy dsl for a long time now)

Tried it out, but it didn’t help. Thanks anyway @ephemient!

[ephemient]

😞

can you check that your kotlin gradle plugin & compiler version at 1.5.10?

i ran into this recently - for me it ended up being that one of the modules that was using compose didn’t explicitly declare kotlinOptions.kotlinCompilerExtensionVersion
