I was attempting to use this on Linux Mint, it doesn't even open, even after setting it to be executable.

Something tells me that you ain't the sharpest tool in the shed.

This is a bukkit/spigot server plugin for minecraft. It is to be ran in the server, it is not an executable.

@ncat1 this is not an executable program. In order to use this, you will need to run a Bukkit/Spigot server. More info about this can be found here: https://www.spigotmc.org/wiki/index/

This is not a standalone program and cannot be run as such, nor is it clientside, so it cannot be run without a server.
