Hi everyone. All of my minecraft servers have been working well and updating easily for a while but an error that started with one and now has seemed to spread to all of them is happening. When I try to download/update Spigot, it ends up throwing a build failure throwing the whole thing off. My research has not yielded much in results since it seems particularly generic. I'll post the failure in below from the console. Thanks for any advice.
