I'm adding compose to a big project with multiple modules (AS 4.1 canary ). I have

buildFeatures {
    compose true
}
composeOptions {
    kotlinCompilerVersion "1.3.61-dev-withExperimentalGoogleExtensions-20200129"
    kotlinCompilerExtensionVersion "0.1.0-dev07"
}

on every module. But when i try to run the project, it appears

Execution failed for task ':app:prepareDebugKotlinCompileTask'.

> org.jetbrains.kotlin.gradle.dsl.KotlinJvmOptions.setUseIR(Z)V

If any module uses both kapt and compose, compiling will fail and complain about IR.

yes, but i knew it worked with kotlinCompilerVersion and kotlinCompilerExtensionVersion

Afaik from when I tried last, adding those two dependencies compiles but is not enough to use compose, adding

compose true

is required but will cause compilation to fail if it conflicts with kapt

ok, thank you. I hoped they had fixed it

this should get fixed once we finish our rebase with kotlin upstream (though i’m not 100% sure), but that is taking a bit longer than we had planned.
