I was trying to build spigot 1.11 in jenkins it was working fine then suddenly it stopped and just started to error out it does the same when just running the commands manually on the same user. Nothing has changed to cause this.  It gave a log report when it crashed and said stuff about patches. I am not too sure what else you want me to give you. If you have any more information ill be happy to give this to you. Thanks Hopefully we can resolve this.
