warning: Kotlin runtime JAR files in the classpath should have the same version

Question

I get the following warning, but I\'m not sure where v1.0.6 resides.

Is it possible this error comes from a Kotlin library somehow including an old Kotlin version?

Answer 1

I fixed warning by overwriting kotlin version used in my app

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'org.jetbrains.kotlin' && requested.name == 'kotlin-reflect') {
            details.useVersion kotlin_version
        }
    }
}

e.g. kotlin_version = 1.3.0
