Fixing the kotlin-android Plugin Issue in Unity3D’s mainTemplate.gradle

If you're working on a Unity3D project and trying to implement Kotlin for Android builds, you might encounter a frustrating roadblock: the Kotlin Android plugin can’t be found during the APK build process. Don’t worry, you're not alone in this, and there’s a straightforward solution.

In this post, we'll go through the problem and how you can easily fix it to enable Kotlin support in your Unity3D Android builds.

The Problem: Missing Kotlin Android Plugin

While exporting your Unity project to Android, you may run into an error indicating that the kotlin-android plugin is missing. This occurs primarily due to incorrect dependencies or plugin configurations in your mainTemplate.gradle file.

Here's an example of what you might see in your configuration:

Upon building, you get an error that states the Kotlin plugin is not found. This usually hints that the environment is missing the correct configurations to locate the Kotlin plugin.

The Solution: Adjusting Your Gradle Configuration

To fix this issue, you need to make some adjustments in the buildscript section of your mainTemplate.gradle. Here’s how to do it:

Step 1: Update Gradle Dependency

Change your dependencies to ensure that the Kotlin plugin is correctly included. Modify the buildscript section as follows:

Step 3: Rebuild Your Project

After making these changes, save the mainTemplate.gradle file and rebuild your Unity3D project. This should resolve the error regarding the Kotlin Android plugin, allowing you to successfully create APKs for your application.

Conclusion

By updating the Gradle configuration in the mainTemplate.gradle file, you're able to integrate Kotlin into your Unity3D Android projects seamlessly. This minor adjustment proves essential when facing issues related to the Kotlin plugin, ensuring your builds go smoothly.
