Reloading a world from a folder

I am currently writing a plugin ot automate matches of the "The Walls CTF Edition" map.

While I have most of the gameplay code done, I realised that I overlooked a big problem which is reloading the map every game. I currently run a server the "The Walls" maps and the plugin I use (and contribute to) uses a special script that copies a backup of the untouched map back to the world folder after stopping the server before restarting it.

I am wondering if there is a way to delete the current (and only) world after the game ends and reload a fresh copy from a folder. (E.g. all players are kicked, world is deleted, world is reloaded, server is restarted with wrapper such as MCMA or Rtoolkit).

I have done a bit of work now and have come up with this :

Code:

public class ReloadMap {
 
    public static void reloadMap() {
        //Kick players
        for (Player pl : Bukkit.getOnlinePlayers()){
            pl.kickPlayer(ChatColor.GREEN + "The server is restarting!");
        }
        //Prevent them from joining
        Bukkit.setWhitelist(true);
        Bukkit.getServer().unloadWorld(TheWallsCTF.wallsWorld, true);
 
        try {
 
            FileUtilities.emptyFolder(new File(TheWallsCTF.wallsWorld));
            (new File(TheWallsCTF.wallsWorld)).delete();
            FileUtilities.copyFolder(new File("WallsCTF"), new File(TheWallsCTF.wallsWorld));
        }
        catch (Exception e) {
            e.printStackTrace();
        }
        //Re allow joining
        Bukkit.setWhitelist(false);
        //Restart the server
        Bukkit.shutdown();
 
 
    }
 
 
 
}

I'm not exactly sure if it's the right way to do it.
