Check Flutter Dependencies
- Make sure your `pubspec.yaml` file doesn’t contain any incompatible or deprecated packages. Update dependencies to the latest versions using:
flutter pub upgrade
- Ensure there are no unresolved dependencies by running:
flutter pub get
Delete Gradle Cache
- Navigate to your project’s directory and remove the build directory to clear any corrupted cache:
cd android && ./gradlew clean
Upgrade Gradle and Android Plugins
- Edit the `android/build.gradle` file and check for the latest version of the Gradle plugin. Update the `classpath` and ensure the distribution URL inside `gradle-wrapper.properties` points to a compatible Gradle version:
// Inside android/build.gradle
classpath 'com.android.tools.build:gradle:3.5.4'
- Ensure the Gradle distribution in `gradle-wrapper.properties` is compatible:
distributionUrl=https\://services.gradle.org/distributions/gradle-6.7-all.zip
Check Java Version Compatibility
- Verify that your JAVA\_HOME environment variable points to a compatible JDK version. For Flutter, JDK 8 is commonly required:
echo $JAVA_HOME
// or
java -version
- If necessary, set the JAVA\_HOME variable to the correct path:
export JAVA_HOME=/path/to/your/jdk
Increase Gradle Memory Allocation
- If you’re having out-of-memory issues, increase the memory allocation for Gradle. Edit `android/gradle.properties` and add or update the following settings:
org.gradle.jvmargs=-Xmx1536M
Check Flutter Build Configurations
- Ensure that the build configurations in `android/app/build.gradle` are set correctly. Make sure the `compileSdkVersion`, `minSdkVersion`, and `targetSdkVersion` match the requirements of your packages and plugins:
android {
compileSdkVersion 30
defaultConfig {
applicationId "com.example.app"
minSdkVersion 21
targetSdkVersion 30
}
}
Rebuild the Project
- Finally, try rebuilding your project. Run the following commands in your terminal:
flutter clean
flutter build apk --profile
- This should resolve the issue with the Gradle task failing. If the problem persists, review logs and ensure that SDK and dependencies are properly configured.
