react-native: Issue building android duplicate versions of jetified-kotlin-stdlib-1

This fix worked for me in the meantime:

dependencies {
     constraints {
        implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.8.0") {
            because("kotlin-stdlib-jdk7 is now a part of kotlin-stdlib")
        }
        implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.8.0") {
            because("kotlin-stdlib-jdk8 is now a part of kotlin-stdlib")
        }
    }
}

(android/app/build.gradle)

I think if using a modern Kotlin Gradle Plugin you can also add the Gradle property kotlin.stdlib.jdk.variants.version.alignment=false (https://kotlinlang.org/docs/whatsnew18.html#usage-of-the-latest-kotlin-stdlib-version-in-transitive-dependencies)

Below fixed work for me.

implementation(platform("org.jetbrains.kotlin:kotlin-bom:1.8.0"))

In my company’s case I did a comparison of the gradle dependency graph to identify what introduced the change in the build dependencies.

The problem, in our case, was introduced by this library’s use of a version wildcard: https://github.com/proyecto26/react-native-inappbrowser/issues/398

And the solution we went with was to specify androidXAnnotation = "1.5.0" as an ext in the android/build.gradle file

I believe this is the same issue I’ve been battling with for a couple of hours now.

* What went wrong:
Execution failed for task ':app:checkReleaseDuplicateClasses'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.CheckDuplicatesRunnable
   > Duplicate class kotlin.collections.jdk8.CollectionsJDK8Kt found in modules jetified-kotlin-stdlib-1.8.0 (org.jetbrains.kotlin:kotlin-stdlib:1.8.0) and jetified-kotlin-stdlib-jdk8-1.4.10 (org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.4.10)

I found a potential fix of upgrading kotlinVersion to 1.8.0 in build.gradle, but that didn’t help. Apparently because React Native has version 1.4.10 on it.

I thought I was the only one, I have also been getting this same issue since today.

this should be the best workaround

Closing as the workaround is reported as working fine.

implementation(platform("org.jetbrains.kotlin:kotlin-bom:1.8.0"))

This worked for me.

This worked for me, thanks!

implementation(platform(“org.jetbrains.kotlin:kotlin-bom:1.8.0”))

Me too. But I sinceraly don’t understand why after creation Java-project with Android Studio’s wizard I have any problems with Kotlin.
