If you’ve been working with React Native, you might eventually need to upgrade your Kotlin and Gradle versions, especially when working with specific libraries like WatermelonDB. In this post, we'll explore the problem you might encounter while updating these dependencies and walk through a step-by-step solution that will enable you to make this transition smoothly.

The Problem: Version Conflicts

When trying to use specific versions of Kotlin (e.g., 1.3.5 or higher), you may run into the following error message:

This error signifies that the Gradle configuration is unable to locate the specified version of the Kotlin Gradle plugin. The root cause of this issue is often related to mismatched versions between the Kotlin Gradle plugin and the Android Gradle Plugin, or even issues with the repositories specified.

To resolve the issue, follow the steps below to update your project files with the correct versions:

Note: Gradle version 6.7.1 is just an example. Always check the compatibility of the Gradle version with your Android plugin version.

Step 3: Sync Your Project

After making these changes, sync your project with the new settings. This allows Gradle to download the necessary dependencies for the updated versions of Kotlin and Gradle.

Step 4: Rebuild Your Project

Finally, do a clean build of your project to ensure all components are properly integrated. You can usually do this from your IDE with options like "Clean Project" or "Rebuild Project".

Conclusion

By following the above steps, you should be able to successfully set the new Kotlin and Gradle versions in your React Native project, allowing you to use libraries such as WatermelonDB without facing version conflict issues.
