Eclipse Plugin for creating large java class diagrams from existing code

I am looking for an Eclipse Plugin to create large class diagrams from existing Java code (free/open source). I found some plugins that create diagrams from java code and vice-versa, but the project has a large number of packages (about 80) and classes/interfaces (about 1000-1500) and I would like to create a diagram for the whole code, with different options (for eg, not to include the interfaces in the generated diagram or to create diagrams for certain packages). I know that the diagram would be very big, but that is what I really want to represent the project in a single diagram (and omitting unimportant classes, interfaces, packages etc and also members and method names).

The project size is impressive. Before you will start with diagrams, try to answer to the following questions:

  • how many diagrams will you create (approximately) ?
  • how much time do you spent on one diagram (average) ?
  • what are total estimated and allowed time effort ?
  • is the result worth of the effort ?
  • is the structure changing ?
  • how much time effort has to be put into diagrams review+fixes after synchronization of model with changed code ?
  • how much time effort has to be put into maintenance of diagrams ?

In case of project of mentioned size, most likely results are not worth of the effort and most likely model and diagrams will be continuously out-dated.

I faced similar situation even with much smaller projects (< 100 class units). I tried some standalone tools - the best was Enterprise Architect (commercial), next - JUDE (currently astah*, but they cut off import functionality from community edition). However, they and other tools didn't discover dependencies, didn't show parametrized types (List<Something>) and didn't show annotations.

So finally I started to use free UML browser/navigator - Class Visualizer. It's like using interactive map versus scanned paper map. It allows to see selected class with all its relations: super-classes, implemented interfaces, sub-classes, referenced classes (associations, dependencies), usages (associations, dependencies). It processes and shows parametrized types and annotations. I can navigate to other classes through relations. Selected class is presented with all details, relations - without. I tried it on projects of your size - diagrams containing hundreds of relations are generated instantly. And its repository is compiled java project, so no problems with synchronization of model with code.

Try ObjectAid UML Explorer. And you should also try JUPE.
