在config把bc选项开了

根据

[11:51:17 WARN]: Unexpected exception while parsing console command "skin"
org.bukkit.command.CommandException: Cannot execute command 'skin' in plugin SkinsRestorer v13.3 - plugin is disabled.

一条可以得出,因为插件已经关闭,所以无法处理命令请求

初步判断是没有使用最新构建!!(与SpigotMC上的最新版本不同)
原帖说明如果你想在1.14.4中使用,必须在Jenkins下载最新构建版本
附上最新构建版本地址
