After two years of refusing to use baselines, because I thought the comparison was much too slow, I wanted to try once again today.
I just created a baseline on a very high level in the project, which I knew would be slow, but I wanted to see how bad it really is.
In fact, it does not work at all. Even after just creating a baseline, no matter whether I make any changes at all, "show differences" will always give me an error "An error occurred during the compare process." and no more information.
I am using EA build 1230 and my project is (still) stored in a *.eap file.
On package level, it works well, but with ~ 1000 packages in my project with a lifetime of only some months, I really don't want to go down to this level, it produces way too much overhead.
At the moment, we still use a simple file copy as a backup. But as we want to go for a cloud solution with future projects, we will need a working version control solution soon.
