Common Causes for "Gradle task assembleDebug failed with exit code 1" in Flutter
- Dependencies Conflicts: A common cause can be conflicts or compatibility issues between the dependencies used within the `pubspec.yaml` file. This can happen when specific library versions are not compatible with one another.
- Incorrect SDK Versions: Having mismatched SDK versions between the Android build tools, Android SDK, and Flutter SDK can cause this error. Ensure all necessary SDK components are aligned for compatibility.
- Build Script Errors: Errors in the `build.gradle` files, such as incorrect or missing configurations in the `android/app/build.gradle` or `android/build.gradle` files, can lead to failures during the build process.
- Code Errors: Syntax errors or issues in your Dart code can sometimes manifest themselves during the build process, causing Gradle task failures. Such issues can include missing semicolons, incorrect import statements, or improper code structure.
- Manifest Issues: Inconsistencies or misconfigurations in the `AndroidManifest.xml` file, such as incorrect package names or missing permissions, can result in build errors.
- Resource Conflicts: When there are conflicting resource files or naming conflicts within the subdirectories of the `res` folder in the Android project structure, Gradle might fail to assemble the debug version.
- Environmental Issues: Settings within your development environment, such as incorrect Java Home configurations or outdated Android Studio installations, might interfere with the Gradle build process.
- Outdated Plugins: Using outdated or deprecated Gradle plugins in your project could cause the build process to fail. Regular updates and maintenance of such plugins are essential for stable build processes.
