Installation of OpenMrs for Developers failure

I have been trying to install the OpenMrs for developers for days or weeks but after the jetty:run has run properly i come to that page and it tells me if i am there, then its because no user interface modules have been installed… i have tried unzipping the refferenceApplication addon and place the modules in the module folder and the owa files into the owa folder but nothing. I even did without and looked out for that String " Using the runtime property…" thing but nothing. What am i doing wrong?
