Gradle threw an error while downloading artifacts from the network.

When Gradle throws an error while downloading artifacts from the network, it can be due to various reasons. Here are some common issues and steps you can take to troubleshoot and resolve them:

Common Causes and Solutions:

Network Issues:

• Ensure you have a stable internet connection.
• Check if your network has restrictions or firewalls that might block Gradle from accessing the internet.

Incorrect Repository Configuration:

• Verify that the repository URLs in your build.gradle file are correct.
• Ensure you’re pointing to the proper repository (e.g., Maven Central, JCenter, or a private repository).

Proxy Settings:

• You may need to configure Gradle to use your proxy settings if you’re behind a proxy. You can do this by adding the proxy settings in the gradle.properties file.
• Example:
  systemProp.http.proxyHost=yourProxyHost systemProp.http.proxyPort=yourProxyPort systemProp.https.proxyHost=yourProxyHost systemProp.https.proxyPort=yourProxyPort

Corrupted Gradle Cache:

• Sometimes, the Gradle cache gets corrupted. You can try clearing the cache by deleting the .gradle folder in your project directory or the global .gradle cache in your home directory.
• After removing the cache, try building the project again.

Dependency Version Issues:

• Check if the versions of the dependencies you are trying to download are correct and available in the repository.
• Sometimes, snapshot versions can cause issues; ensure you use stable versions of the dependencies.

Gradle Wrapper Version:

• If you’re using the Gradle Wrapper, the issue might be with the version of Gradle. Try updating the Gradle Wrapper to a newer version.
• You can update the wrapper using the command: ./gradlew wrapper --gradle-version=<new_version>

SSL/TLS Certificate Issues:

• If the error is related to SSL/TLS, there might be a problem with the certificate chain. This can happen using a private repository with a self-signed certificate.
• You can configure Gradle to trust your certificate, but be cautious with this approach as it can introduce security risks.

Check the Error Message:

• The error message provided by Gradle can often give you specific clues about what’s going wrong. Look for any hints in the error message that might point to the root cause.

Gradle Daemon Issues:

• Sometimes, the Gradle Daemon can cause issues. Try stopping the daemon using ./gradlew --stop and then rerun your build.

Additional Tips:

• Run the build with the --info or --debug flag for more detailed output, which can help in diagnosing the problem.
• Ensure that your build script is compatible with the version of Gradle you are using.
• If you’re in a corporate environment, check with your IT department to see if any additional configurations are required for network access.

If you continue to face issues, consider sharing the specific error message or log output, as that can provide more precise guidance for troubleshooting.
