Open multiple Eclipse in Mac

By default, you can’t open 2 Eclipse at the same time from UI operations.

I would like to open 2 workspace( I separated workspace for Server application and Client application).
In that case, you can open with console

How?

Open console(bash)
Go to your eclipse root(Eclipse.app exists)

open -n Eclipse.app

-n is key part for it. You can select workspace.
