To fix the Gradle sync error, follow these steps:

1. Replace JCenter with Maven Central: In your build.gradle file, update the repository section to:

repositories { google() mavenCentral() } // Replace JCenter with Maven Central

2. Clear Gradle Cache: Run the command to clean the Gradle cache:

./gradlew cleanBuildCache

3. Check Network/Proxy: Ensure your new machine has the correct network settings and no proxy is blocking the connection.

4. Update Gradle Version (Optional): Update Gradle by running:

./gradlew wrapper --gradle-version <latest_version>

5. Use SSL Trust > To do this temporarily, add this to your gradle.properties:

systemProp.gradle.ssl.verify=false
