DzusillCore is a reusable Paper plugin framework designed to eliminate boilerplate so that developers can focus on plugin logic rather than infrastructure. Whether you are building a simple utility plugin or a large, production-grade server feature set, the framework provides the same composable building blocks.
DzusillCore is built around four classic OOP pillars applied consistently across every subsystem:
| Principle |
How it appears in the framework |
| Abstraction |
CorePlugin, AbstractModule, Menu, AbstractSqlRepository — base classes that define shape, not content |
| Inheritance |
Concrete plugins/modules/menus extend the abstract bases and override only what differs |
| Polymorphism |
DataStore, Database, ArgumentType, MenuTemplate — uniform interfaces with interchangeable implementations |
| Encapsulation |
ServiceRegistry, HookManager, CommandRegistry — internal wiring hidden behind clean APIs |
| Area |
Key classes |
| Plugin bootstrap |

| Commands |
