Creating a new project

  • We use Maven’s empty project, created directly without any templates




  • Input project information




  • Idea automatically removes the line and adds it itself




  • Create an empty Maven module in the project as follows:




  • Parent project dependency file: use dependencyManagement for dependencyManagement
