I am on a mac, but I don\'t think it will make a difference. I have a directory that I want to fully import/add into Eclipse. What I did is this:
The thing that works best for me when that happens is :
Create a new eclipse project(JAVA)
Take your source file (contents of the src folder!!!) and drag from finder and drop into the src folder in eclipse IDE
Make sure you add your external jars and stuff and tada you're done!!
