Error: Execution failed for task ‘:app:compileFlutterBuildRelease’.
This error occurs when the release build process of your Flutter application fails.
Cause of the Error:
There can be several reasons behind the failure of the release build task. Some common causes include:
- Invalid configuration in the build.gradle file
- Incompatible or missing dependencies
- Issues with your Flutter SDK or Flutter version
- Insufficient system resources
- Problems with the code or project structure
Solution:
To resolve the “Execution failed for task ‘:app:compileFlutterBuildRelease'” error, you can try the following solutions:
- Check build.gradle file: Ensure that the build.gradle file in the android/app directory is correctly configured. Verify that the targetSdkVersion, compileSdkVersion, and minSdkVersion are set appropriately.
- Sync Gradle and update dependencies: Open the android directory of your Flutter project in Android Studio. Gradle will automatically sync and download any necessary dependencies. If there are any updates available, Android Studio will prompt you to update them.
- Upgrade Flutter SDK: Make sure you are using the latest stable version of the Flutter SDK. Run the following command in your terminal:
flutter upgrade - Check system requirements: Verify that your system meets the minimum requirements to run Flutter properly. Ensure that you have enough memory and disk space available.
- Review and debug your code: Examine your code for any potential issues or errors. Check your project structure, imports, and syntax. Utilize debug tools to identify and fix any runtime errors.
If none of the above solutions work, it can be helpful to search for the specific error message or stack trace provided in the error log. This can provide more insights into the root cause of the issue.
Example:
Here is an example of an error message:
{@code
Execution failed for task ':app:compileFlutterBuildRelease'.
> A problem occurred configuring project ':app'.
> Could not download runner.jar (io.flutter:runner:1.0.0).
> Could not get resource 'https://storage.googleapis.com/download.flutter.io/io/flutter/runner/1.0.0/runner-1.0.0.jar'.
> Could not HEAD 'https://storage.googleapis.com/download.flutter.io/io/flutter/runner/1.0.0/runner-1.0.0.jar'. Received status code 502 from server: Bad Gateway
}
In this specific example, the error message indicates an issue with downloading the runner.jar file required for the release build. It suggests a network-related problem with the server.
