This error can halt your development, leaving you scratching your head. But don’t worry! In this guide, we will guide you through resolving this issue step by step.

Understanding the Problem

What this means is that your project’s build process via Gradle failed due to an inability to retrieve the required Kotlin compiler artifact from the repository. This can be a frustrating experience especially since you may not possess any antivirus software to interfere with the connection.

Key Symptoms:

Disturbance in Gradle build tasks.

Unable to download artifacts from Maven repositories.

“Connection refused” errors when accessing repository URLs.

Solution to the Problem

Here’s how you can effectively resolve the kotlin-compiler-embeddable download issue. The following steps will guide you through the process:

Step 1: Change Your Kotlin Compiler Version

Sometimes, the version of Kotlin being used might not be compatible or could be facing issues with connectivity. Here’s how to change the version:

Open your project's android/build.gradle file.

Look for the ext.kotlin_version line.

Change the version of Kotlin to a stable and supported version. For instance, if 1.5.21 is causing problems, you might want to switch to 1.5.30 or another newer version.

Step 2: Check and Modify HTTP Settings

This step focuses on ensuring your project settings permit a direct connection to the repository.

Open Android Studio.

Navigate to File Settings (or Android Studio Preferences on Mac).

Go to Appearance & Behavior System Settings HTTP Proxy.

Select 'No Proxy' to avoid any cross-network issues which might block your connection.

Step 3: Clean and Rebuild Your Project

After making the above changes, it's crucial to clean and rebuild your project to ensure all settings take effect.

Go to the Build menu.

Select Clean Project.

After cleaning, select Rebuild Project.

By following these steps, you should be able to successfully download the required Kotlin compiler and resolve any build errors you encountered.

Conclusion

In conclusion, encountering errors like the kotlin-compiler-embeddable-1.5.21.jar download issue can be frustrating. However, by changing the Kotlin version and adjusting your HTTP settings, you can troubleshoot and resolve these errors effectively. With this guide, you can get back to focusing on creating an amazing Flutter application without further interruptions.
