I see the problem. Actually, this job is accidentally mixing up two options by giving them the same short name, -i. You are correctly using -i as short for -input (which works, good), but it's also using -i for -itemsFile which is something else.
Sebastian, how about I just remove their short forms, for -itemsFile and -usersFile? Yes, that's just what -usersFile means. (And -itemsFile means something analogous.)
