I want to import project A to eclipse(GGTS),but I already have A which is an old version but of same name. When I use import existing project, it automatically combine two version together but I don't want this happen. I also use git so I'm not sure what make this happen.
It's a bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=40493
But you can try to change the name tag in the .project file in the project before importing it.
