Skript Not Working on Bukkitcraft localserver

Hi i made a bukkitcraft localserver to test my skripts but the skript plugins doesn't work. I know they work for spigot because i had a free server on a free server host.

The Skript Plugins:

SharpSK_1
SkQuery_3
skRayFallv1.9.12
Skript
skUtilities.v0.9.2
TuSKe_1

Console Error:
