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?

Hello,
you should try to proceed in two steps as Hugo suggests : java source -> java reduced model -> kdm model.
The parameter to set for Java discoverery step is the one named "INCLUDED_ELEMENTS_REGEX" in ui. In the Java discoverer api, it can be set with the .setIncludedElementsRegEx(String regex) method.
The regex parameter allows to indicate a regular expression on qualified names for elements (types & packages) to be included during analysis.
For instance, if you want to select only types from pkga.pkgb.pkgc, you sets the value to pkga\.pkgb\.pkgc\..*
(there is also one opposite parameter EXCLUDED_ELEMENTS_REGEX)
I hope it will be helpful.
regards,
Fabien.
