Conflict with dependency...Resolved versions for app (1.0.2) and test app (1.0.6) differ

[sevar83]

Kotlin 1.0.6
Android Studio 2.3.0-canary 3

testCompile "com.nhaarman:mockito-kotlin:1.1.0"

Error:Conflict with dependency 'org.jetbrains.kotlin:kotlin-stdlib' in project ':app'. Resolved versions for app (1.0.2) and test app (1.0.6) differ. See http:https://g.co/androidstudio/app-test-app-conflict for details.

Mockito-Kotlin depends only on 1.0.6, so the dependency conflict should be on your side. Do you have any dependencies that depend on 1.0.2? If so, you can try using a ResolutionStrategy to force 1.0.6 on them.

Do you have any dependencies that depend on 1.0.2?

I guess RxKotlin is the culprit. Could you tell me how to use ResolutionStrategy please?

[nhaarman]

An easier way is to just depend on the stdlib yourself explicitly:

compile 'io.reactivex:rxkotlin:0.60.0'
compile "org.jetbrains.kotlin:kotlin-stdlib:1.0.6" // This overrides the 1.0.2 dependency in RxKotlin
testCompile  "com.nhaarman:mockito-kotlin:1.1.0"

Or, using a Resolution strategy:

dependencies {
    compile 'io.reactivex:rxkotlin:0.60.0'
    testCompile "com.nhaarman:mockito-kotlin:1.1.0"
}

configurations.all {
    resolutionStrategy {
        force 'org.jetbrains.kotlin:kotlin-stdlib:1.0.6'
    }
}

I had a very similar problem and I'm also familiar with this already but anyways I did it wrong. Posting here for others to find out if they have the same issue.

We are using kotlin-stdlib-jre7. That's why I was forcing that dependency to be the dependency I want. But they are of course not the same and resolutionStrategy.force just matches if they have the same group and the name.

So make sure that you are forcing kotlin-stdlib just like mentioned here.

I've found a way to solve this issue using the following:
testCompile "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"

Hope it works for you too.
