You would have to map the folders in a network drive so that your computer sees them as available on the local file system and then set up a project that points to them there.
It would work, but it might not be very performant.
Of course you know I am obligated to bring up that multiple developers working on the same shared sever is a terrible idea and is prone to errors, right?
Right, the performance dies which is why we're using RDS instead of just getting to it thorugh a mapped drive.
Indeed it is. Some things never change though.
Then I am afraid you are out of luck. Eclipse is designed to work with local projects.
I suspect that you're only hope would be to set up local projects that automatically synchronize with the shared server so that, essentially, when you save something to your local machine it automatically copies it to your server. Perhaps somethignlike rsync or DeltaCopy.
Still a bad model.
