Upgrade some maven plugins and enable google-java-format

[pin-yu]

Briefly describe what I've done

• Upgrade maven plugins
• Enable google-java-format (I use spotless as a maven plugin to enable google-java-format)
  • Using ratchetFrom mode. In this mode, only those modified files will be applied google-java format. The other files will remain the same.
  • The license will be automatically added to the top of the modified files and the time in the license will be upgraded.
  • more information
• Passed full tests.
