I'm developing a project with Eclipse 4.21, unfortunately this version doesn't allow ObjectAid to work properly, I don't know why. After many attempts, I found out that ObjectAid doesn't work anymore after Eclipse 4.19.
I don't want to reinstall and configure Eclipse again for my project. So, can I have two Eclipse opened on same workspace / same project at same time? Using one (4.21) to develop and one (4.19) just to generate UML class diagram (using objectaid) without problems.
