Developing Qt applications with Eclipse on Ubuntu

Hello. I am starting developing Qt applications with Eclipse IDE v3.7.2 on Ubuntu 12.04 and came across several difficulties. I've installed and built Qt 4.8.2, set environment variables according to the Nokia installation guide, installed CDT and Qt Eclipse Integration Plugin. I made the "projects" directory in /home/<username>/, there I copy existing projects. I noticed I can build Qt applications via command line, but when I try to import .pro file to Eclipse I get the following error: Parent of resource: /home/<username>/projects/addressbook/.project is marked as read-only.

I believe it's a newbie problem, could, please, somebody help me out with this?
