Issue
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.
Solution
No, you can't run two versions of Eclipse at the same time accessing a single workspace. The second Eclipse you try to start will refuse to access the workspace saying it is already in use.
Trying to run an older version of Eclipse on a workspace that has been modified by a newer version will also produce an error.
You can run multiple versions on separate workspaces.
