Android Studio 1.1.0 Gradle project sync failed Error importing a Gradle project on a OSX
Introduction
This article addresses the common error “Gradle project sync failed” encountered when importing a Gradle project in Android Studio 1.1.0 on OSX. This error can stem from various factors, including network connectivity, outdated Gradle versions, and improper configuration settings. We’ll delve into potential causes and offer effective solutions to resolve this issue.
Troubleshooting Steps
1. Check Network Connectivity
- Ensure a stable internet connection as Gradle downloads dependencies from remote repositories.
- Try restarting your router or modem.
- Check if your firewall is blocking any necessary connections.
2. Update Gradle Wrapper
- Open your project’s `gradle/wrapper/gradle-wrapper.properties` file.
- Verify the `distributionUrl` property, ensuring it points to a compatible Gradle version.
- If outdated, update the version number and sync the project again.
3. Manually Download and Install Gradle
- If automatic Gradle downloads fail, manually download the desired Gradle version from [https://gradle.org/releases/](https://gradle.org/releases/).
- Extract the downloaded archive.
- Set the `GRADLE_HOME` environment variable to the path of the extracted Gradle directory.
- Add `$GRADLE_HOME/bin` to your system’s PATH environment variable.
- Sync the project again.
4. Update Android Studio
- Outdated Android Studio versions may lack compatibility with newer Gradle versions.
- Update Android Studio to the latest version.
- Sync the project after updating.
5. Check Gradle Daemon Configuration
- The Gradle daemon can sometimes cause conflicts. Try disabling it by setting `org.gradle.daemon=false` in your `gradle.properties` file.
- Alternatively, you can adjust daemon settings within Android Studio’s `File > Settings > Build, Execution, Deployment > Gradle`.
6. Clean and Rebuild Project
- In Android Studio, navigate to `Build > Clean Project`.
- Follow this with `Build > Rebuild Project` to rebuild the project from scratch.
7. Invalidate Caches/Restart
- Go to `File > Invalidate Caches / Restart`.
- Select `Invalidate and Restart`.
- This option refreshes caches and often resolves configuration issues.
8. Update JDK
- Check your Android Studio’s JDK configuration.
- Ensure you have a compatible JDK version installed (usually Java 8).
- If necessary, update your JDK or set the correct path in Android Studio settings.
9. Inspect Error Logs
- Review the error messages in the Android Studio console window for specific details.
- Examine `build/logs` in your project directory for detailed logs that might indicate the root cause.
Common Error Scenarios and Solutions
Scenario: Offline Mode
- If you’re working offline, Android Studio’s default setting is to use cached dependencies. Ensure you have all required dependencies cached.
- You can enable offline mode in `File > Settings > Build, Execution, Deployment > Gradle` and check the box for “Offline work.”
Scenario: Corrupted Gradle Files
- Delete the `.gradle` directory in your user home directory.
- Invalidate caches and restart Android Studio.
- This action forces Android Studio to re-download Gradle files.
Example: Gradle Project with Incompatible Gradle Version
distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip
- This example shows a Gradle wrapper configured to use an older Gradle version. You’ll need to update this version to a compatible one.
- For example, you could update to `distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.4-all.zip` for Gradle 5.6.4.
