hey how do you opt into the new IR backend , for a multi module android project

[samuel]

android {
   kotlinOptions {
       useIR = true
   }
}

Apply this to your modules

sigh there is no way to just apply it globally?

Maybe there is a way, but this is how i did it. My setup is such that i have a common gradle file that i use for settings like this that will be common to all library modules, so i only have to declare this in two places (common + app)

subprojects {
    tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).configureEach {
        kotlinOptions {
            useIR = true
        }
    }
}

Put this in your project level build.gradle to enable IR backend for all the modules.
