Hi there,

I’m having a problem reverse engineering UML from Java classes. I’ve not used this feature before so forgive me if I’ve missed something obvious.

I create a new UML repository, select reverse engineer UML from Java, select the source files I want to use, click okay and the process starts. There is some progress and then I get an error message stating: “Creation of element failed. Bad version number in .class file”. I have tried selecting different sets of source files and I usually get this error (I’ve only had one successful run with a small set of source files).

Here’s my installation information:

marinovm,
It seems like you are following the correct steps. You should try using the -clean and check if it fixes the issue:-
https://www.genuitec.com/forums/topic/troubleshoot-using-the-clean-command-line-argument/

Incase the problem persists, can you switch to a new workspace and try reproducing this issue. Let me know what result you get.
