[Help] Can someone bypass this jar?

[MariyanPRO]

Hello.
I'm playing in one bulgarian server called hardcraft.
Server got anticheat and if you don't have it you can't play in PvP Worlds.
I want help to bypass this anticheat and to put nodus in it.
If someone can help me write here.
I'll upload download link if you need.
