Kotlin gradle Could not initialize class class org.jetbrains.kotlin.gradle.internal.KotlinSourceSetProviderImplKt

Question

I tried to use gradle for transpiling Kotlin to Js. When I run the example from https://www.codeflow.site/fr/article/kotlin-javascript I got the error : Could not initia

Answer 1

in my case it solves the problem:

buildscript {
    ext.kotlin_version = "1.3.72"
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

    }
}

set ext.kotlin_version = "1.3.72" and $kotlin_version

Answer 2

I don't know if I can do the same as KP7984 said - to check the versions of the plugins of my Android Studio, not the ones of my OS. I use gradlew -v of my project instead of gradle -v and it works for me.

Answer 3

In your build.gradle file if you hover over the classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" it will tell you what version of Kotlin you will have to use in the kotlinVersion variable at the top of the file, according to your SDK/plugins versions.

Answer 4

I just had the same issue. On windows, I checked the kotlin version from the command line with gradle -v and then adjusted the kotlin version in build.gradle of my project to match my version of gradle.

I hope this works for you too.

Answer 5

In Android Studio: File -> Project Structure -> Variables

There edit the kotlin_version to e.g. 1.3.72

Gradle should resync automatically, otherwise resync manually

Answer 6

Solved this issue by setting the latest Kotlin version (1.3.72) in build.gradle file.

buildscript {
ext {
    kotlinVersion = '1.4.20'
    springBootVersion = '2.0.4.RELEASE'
}
repositories {
    mavenCentral()
}
... 
}
