Chapter 2 building CRM project development environment (building development environment)

2.2 Build development environment

2.2.1 establish crm project

Use IDEA establish Empty Project, As a workspace for the project

2.2.2 establish crm modular

establish maven Type of module , As a development project

2.2.3 Add... To the project meaven rely on
