The Java project code management system provides a code managing and analyzing platform for development teams. Developers can upload projects and modify files online to achieve more efficient communication and cooperation. In addition, after the project was uploaded, the system analyzes the codes in the project to extract the class relations, package relations, and method invocation relations. Developers can view class diagrams, package diagrams, and method invocation diagrams on the web page to get a more intuitive and efficient development experience.

Requirement analysis is an essential part of requirement engineering, and drawing UML diagram is one of the important means of requirement analysis. In order to make it possible to automatically generate UML diagrams according to the collected and preprocessed system requirements, an open-source and easy-to-use UML modeling system must be built. Because some existing UML modeling systems are not open-source or too complex to carry out secondary development, we want to design and develop a UML modeling tool system that can connect with the existing requirements management and analysis system established by the research group.
