"no main manifest attribute in craftbukkit.jar" halp?

So, me and my friend were trying to make a ctf gamemode for fun, and when he attempted to run it, it said "no main manifest attribute in craftbukkit.jar"; And also I can only download the beta builds from www.dl.bukkit.org(1.7.9)

 

I'm fairly sure you need CraftBukkit not Bukkit.

 

Be sure your file name is craftbukkit.jar so many people forget to delete all the numbers at the end of it.

 

Make sure that the server is using a CraftBukkit.jar file and not just a plain Bukkit.jar. They are not the same thing.

As for downloads, CraftBukkit itself is not currently available due to the DMCA takedown. So if you don't already have a CraftBukkit file from before they were removed, you're going to have a hard time starting a server.

 

The CraftBukkit JAR files are all corrupt for a reason what JaguarJo said.
Just use Spigot. Is just like Bukkit

 

Or you can get CraftBukkit from other places, If you want, you can borrow my copy of craftbukkit 1.7.9

 

You cannot get Spigot either. It uses CraftBukkit.
