is there a way to do something like this for all modules in a project?

// ignore these warnings
kotlin.target.compilations.all {
    allKotlinSourceSets.forEach { sourceSet ->
        sourceSet.languageSettings.apply {
            useExperimentalAnnotation("kotlinx.coroutines.FlowPreview")
            useExperimentalAnnotation("kotlinx.coroutines.ExperimentalCoroutinesApi")
            useExperimentalAnnotation("io.ktor.util.KtorExperimentalAPI")
        }
    }
}

thats more suitable for #gradle ,but look here: https://docs.gradle.org/current/samples/sample_convention_plugins.html#compiling_convention_plugins

You can declare the same thing in allprojects {} block in your root project

i'm not sure whats i should be using in that link? doesn't seem to be very relevant I have tried in the

allProjects

block but

kotlin.target

is unrecognized

kotlin.target is not recognised because you need to apply kotlin plugin in root project too

@Big Chungus which kotlin plugin do i need to apply in the root project? multiplatform if i'm in a multiplatform project?

Yes

plugins {
 kotlin("multiplatform") version "1.4.31" apply false // apply false is optional. This will register plugin APIs, but will not actually apply it to the rootModule, still allowing you to configure subprojects in it
}

hmm i've tried that but i'm still getting

Unresolved reference: target

in

kotlin.target.compilations.all

As you can see it does recognise kotlin, but not target try targets

targets

doesn't work. i also don't think it is recognizing kotlin properly. it goes to the package when i click it. when i click the

kotlin

in one of my android modules it goes to a gradle kotlin file

Might be just your ide then

what is the DSL builder?

allProjects is no longer recommended. “Another, discouraged, way to share build logic between subproject is cross project configuration via the 

subprojects {}

 and 

allprojects {}

 DSL constructs.”
