[TOP1FORCEY]

hello, me and my freinds used this bot for about a week, realy nice bot by any means but i decided to tweak some things like mandatory vote for skiping song, etc. So i did everything i needed to do, and wanted to compile it but this happens https://imgur.com/a/fRko6gW
so most of the thing are abscent from MANIGEST.MF and jar is refusing to run without it. Please i need help.
