You should have a .exe file
In eclipse, right click on project, go to properties, Java Build Path, add External Jars, and add the .exe file.
the .exe can then be moved to a convenient place, preferably:
(users, you,) git, location of github local project, and in a library folder (you may have to create this folder, other external libraries such as WPILib and json_simple-1.1).
Also, a good directory to try if you can't get the .exe to work properly in eclipse is
(users, you,) wpilib, user, java, lib.
According to https://www.chiefdelphi.com/forums/showthread.php?p=1625835 , this lib folder in the wpilib directory folder is automatically implemented into the eclipse robot projects
