Apple M2 MacOS Ventura

Any idea how to fix it?

Use a newer version of protoc. This isn't a problem with the plugin; the older protobuf versions didn't support aarch64 on Mac.

@ejona86 hi!

I updated protoc to the newest version but still get a similar error. What do I do wrong?

Here is my setup:

import com.google.protobuf.gradle.id

val grpcKotlinVersion = "1.4.1"
val grpcVersion = "1.61.0"
val protobufVersion = "3.25.2"

plugins {
    kotlin("jvm")
    id("com.google.protobuf")
}

repositories {
    mavenCentral()
}

dependencies {
    api("io.grpc:grpc-kotlin-stub:$grpcKotlinVersion")
    api("io.grpc:grpc-protobuf:$grpcVersion")
    api("io.grpc:grpc-netty:$grpcVersion")
    api("com.google.protobuf:protobuf-kotlin:$protobufVersion")
}

kotlin {
    jvmToolchain(17)
}

protobuf {
    protoc {
        artifact = "com.google.protobuf:protoc:$protobufVersion"
    }
    plugins {
        id("grpc") {
            artifact = "io.grpc:protoc-gen-grpc-java:$grpcVersion"
        }
        id("grpckt") {
            artifact = "io.grpc:protoc-gen-grpc-kotlin:$grpcKotlinVersion:jdk8@jar"
        }
    }
    generateProtoTasks {
        all().forEach {
            it.plugins {
                id("grpc")
                id("grpckt")
            }
            it.builtins {
                id("kotlin")
            }
        }
    }
}

The error:

I found few related issues and just installed Rosetta 2 by the following command in Terminal:

softwareupdate --install-rosetta --agree-to-license
