I'm trying to reverse engineer a big legacy project with MoDisco eclipse plugin. Tried doing a Java to KDM model discovery, but it failed because Java heap space got filled. So i increased the amount of memory, but now discovery process seems to be getting stuck at "Saving discovered model".

If i go and select single Java package from my project, only option i get for discovery is "KDM source" and that one doesn't contain any information about class relations etc.

Is there a way to create a KDM model from only some small part of Java project? Or is there some way to improve KDM discovery performance, when dealing with huge project?

A solution is to work in two steps:

  1. Discover the Java model by selecting only the packages you need (cf. the corresponding parameters in the launch configuration of the Java discoverer);
  2. Transform this reduced Java model into the KDM model.

I hope this helps.
