"the server jar file" I don't think you know what you're asking for here. dare I ask why you're asking for it?
I have a server, and craftbukkit is down because of legal issues, im asking for the bukkit jar of the server, so that I can have my server at 1.8.
the server is not (yet) running a 1.8 bukkit.jar or whatever you want to call it. its in fact running on SpigotMC. they have just now released a 1.8 version supported server software. find spigotMC 1.8 in this thread http://www.spigotmc.org/threads/bukkit-craftbukkit-spigot-1-8.36598/ also please do not talk about other servers on here thanks. locking.
