You sir.. Have a logic error. You never connect up anything so the program is a dead program.. The error your getting is hoping you will go find the line in your code and debug it with the debugging window in eclipse. Set break points and find exactly what line.. I think you'll be amazed at where your logic error is. You have no type of speed controllers set. You have no place where your mechanum drive is hooked up to your motors. Try those first.
