Additional Repository Configuration (if needed):

Conclusion

Encountering the Gradle task assembleDebug failed with exit code 1 error can be frustrating, especially when integrating commonly used packages like Firebase. However, with a careful examination of your configuration files and correcting minor errors, you can usually resolve the issue swiftly.
