[Paulius Ruminas]

Hello, i’m trying to make a compiler plugin for kotlin native that generates Deferred return type methods for suspend functions e.g.

suspend fun foo(): String = "Hello world!"

would generate an additional method

fun foo(scope: CoroutineScope): Deferred<String> = scope.async { "Hello world!" }

As i try to hook into ir codegen i’m getting this exception:

exception: java.lang.IllegalStateException: The provided plugin com.nfq.NativeSuspendRegistrar is not compatible with this version of compiler

My build.gradle looks like this:

apply plugin: 'org.jetbrains.kotlin.jvm'
apply plugin: 'kotlin-kapt'

repositories {
    jcenter()
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlinVersion"
    implementation "org.jetbrains.kotlin:kotlin-compiler-embeddable:$kotlinVersion"

    compileOnly 'com.google.auto.service:auto-service:1.0-rc4'
    kapt 'com.google.auto.service:auto-service:1.0-rc4'
}

And my ComponenRegistrar looks like this:

@AutoService(ComponentRegistrar::class)
class NativeSuspendRegistrar : ComponentRegistrar {

    override fun registerProjectComponents(project: MockProject, configuration: CompilerConfiguration) {
        IrGenerationExtension.registerExtension(project, NativeSuspendIrGenerationExtension())
    }
}

I use Kotlin 1.3.11

I just had this exact issue… the solution is to change your dependency on kotlin-compiler-embeddable to kotlin-compiler in your build.gradle

Hi, i'm having the same issue (using kotlin-compiler and not kotlin-compiler-embeddable), @Paulius Ruminas, did you find a solution?

[Daniele Bartorilla]

i solved switching back to the embeddable artifact and building directly using gradle and not with intellij
