KMM : How to resolve Incompatible abi version. The current default is '1.4.2', found '1.5.0'. The library produced by 1.5.20 compiler?

Question

I am producing a KMM application, I have already done the Android part without any problems, everything works perfectly.

Nevertheless, when I launch the iOS version, by opening the iosMyApp.xcworkspace file, and I launch the compilation, this error appears.

The following Kotlin source sets were configured but not added to any Kotlin compilation:
 * androidAndroidTestRelease
 * androidTestFixtures
 * androidTestFixturesDebug
 * androidTestFixturesRelease
You can add a source set to a target's compilation by connecting it with the compilation's default source set using 'dependsOn'.
See https://kotlinlang.org/docs/reference/building-mpp-with-gradle.html#connecting-source-sets

Currently, I have nothing in the iOS part.

Here is the configuration of my project. build.gradle.kts (:shared)

import org.jetbrains.kotlin.gradle.plugin.mpp.KotlinNativeTarget

    kotlin("multiplatform")
    kotlin("native.cocoapods")

        val iosMain by getting {
            dependencies {

            }

    }
}

android {
    compileSdk = 31
    sourceSets["main"].manifest.srcFile("src/androidMain/AndroidManifest.xml")
    defaultConfig {
        minSdk = 23
        targetSdk = 31
    }
}

build.gradle.kts

buildscript {
    repositories {
        gradlePluginPortal()
        google()
        mavenCentral()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:7.1.0-alpha12")
        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.10")
        classpath("com.apollographql.apollo:apollo-gradle-plugin:2.5.9")
        classpath("com.google.dagger:hilt-android-gradle-plugin:2.38.1")
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
        maven("https://jitpack.io")
    }
}

tasks.register("clean", Delete::class) {
    delete(rootProject.buildDir)
}

I tried to modify this line for an older version but without success.

implementation("io.ktor:ktor-client-ios:1.6.3")

Does anyone have a solution or anything to investigate? 😊

Answer 1

I have faced similar issue in the KMM project with iOS project.

Incompatible abi version. The current default is '1.5.0', found '1.6.0'. The library produced by 1.6.21 compiler ios

I have resolved by upgrading gradle version in application gradle

classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.31")

replaced with

classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.21")

if still getting problem, upgrade kotlin gradle and kmm plugin in the plugins section

Answer 2

I was able to solve this issue by updating Kotlin from 1.5.10 to 1.5.20.
