After compiling spigot, hitting “copy to server” on the spigot/craftbukkit screen copies buildtools.jar into server directory, not the spigot jar as it should.
Upon further inspection, it failed the first time, but after manually deleting build tools and pressing copy again, it copied both craftbukkit.jar and buildtools.jar
Perhaps this is a bug?
More likely it wasn’t quite done compiling craftbukkit.jar. This takes more time than one would think. At the bottom of that page the output of the compile operation is shown. If you presscopy before that output states it has completed successfully, it will only copy buildtools.jar, since the other file do not yet exist.
Ahh. Good to know! I assumed the creating jar message meant it was done.
