Introduction

Paper’s command system is built on top of Minecraft’s Brigadier command system. This system provides a powerful and flexible way to define commands and arguments. It offers many advantages above the previously widely used Bukkit command system:

• Less parsing or error checking required by the developer for arguments.
• Better user experience with client error checking.
• Integration with reload events, allowing the definition of commands usable in datapacks.
• Easier creation of subcommands.
