Ok, So minicraft it is.
Do you get errors importing, or compiling or executing?
If you tell us exactly which phase, and post the errors we may help.
Also, importing into eclipse may require a .project file. if minicraft is not in this format, you are in for a hard time.
If it's
maven based, you can run: mvn eclipse:eclipse
i just don't know enough from your post or about minicraft to help you at this point.
