This is a simple Spigot 1.8 plugin for the KnockbackFFA gamemode. Some features may be buggy and the plugin isn't well optimised. You're free to use this as a placeholder for your own KnockbackFFA plugin as long as you respect the license.
Just import this into your favorite Java IDE (such as IntelliJ Idea) and run the equivalent of mvn package, such as the "Lifecycle -> Package" button on IntelliJ.
Just drag this in your Spigot (1.8 forks are usually supported, use them at your own risk), start your server, configure the plugin at "Plugins -> CopperKnockbackFFA -> config.yml" and restart your server.
PlaceholderAPI is recommended for placeholders. Note: some of the Placeholders may not be implemented in the plugin.
