7. © 2024- atWare Inc. Multi-Project Build の魅力 - 依存関係の制御 - sub-project の独立性 - domain, application の再利用性 - パフォーマンス向上
8. © 2024- atWare Inc. Project structure
9. © 2024- atWare Inc. Project structure (all) - buildSrc build conventions - app bootable (AppMain.class) - lib: - presentation - application-service-interface - application-service - application-data-interface - data-adaptor - domain - composite project: - util
10. © 2024- atWare Inc. Project structure (simplified) - presentation *Controller, view - application-service-interface interface *Service application I/O - application-service *ServiceImpl - application-data-interface interface *Repository - data-adaptor *RepositoryImpl
