Trying to reverse-engineer existing project and it would be of great help to see how classes collaborate/depend on each other. Is there a way to build project-wide UML diagram (or class diagram of any kind) in IntelliJ IDEA using build-in functionallity or using some free plugin?
Right click on your package no matter which. Click Diagrams > Show Diagram (Ctrl+Alt+Shift+U). You will see your package in diagram editor.
Now:
- You can
expand(E) orcollapse(C) all nodes. - You can show dependencies
- You can show many attributes of nodes (constructors, methods, properties...)
- You can drag&drop other packages from project explorer.
So, play with it a bit and i think you will achieve what you need.
This is how it could looks like:
