When A project is copied the include paths are modified. I make all my paths relative to my project. So it can be imported to another workspace. With a copy of a project e2studio fills in the absolute paths.
Please add a checkbox "Do not modify paths".
You should not just copy projects but you should use Export - Import to move projects.
File > Export > General > Archive File
File > Import > General > Existing Projects into Workspace
Thansk for the reply.
It is a little more work, but ik works.
Still i don't like this feature, all versions of eclipse I was used to did not touch my settings.
By the way: I tried to install the e2 studio in eclipse Juno, but I got a lot of (java?) errors. ( windows 8, latest java).
Up to date e2studio is implemented only in Helios. It does not work with Juno yet. A Juno version should come beginning of Q2 2013.
