Resetting world

Hi!
Sorry for my english, but I'm from Poland (I use google translator)

I want to do, so that when you type the command /restart, resets my map called "castle".
This is my code:

Code:

final World w = ca.getSpawn1().getWorld();
            final String name = w.getName();
 
 
         
            if (Bukkit.getServer().unloadWorld(w, false)){
                System.out.print("<--------------- UNLOADED");
            } else {
                System.out.print("<--------------- ERROR");
            }
         
            Bukkit.getScheduler().runTask(Main.getPlugin(), new Runnable(){
            @Override
            public void run() {
                WorldCreator wr = new WorldCreator(name);
                wr.copy(w);
                wr.createWorld();
             
                // TODO Auto-generated method stub
             
            }});

Everything is working, but when I do this the second/third etc time I get info "<------- ERROR"/
I must to do restart/reload server. Why?

Sorry for my english :/

 

You should keep a reference/copy of the world outside of the folder of worlds, then when you unload you just delete / load a copy of the "base" instance.

 

My code:

Code:

if (Bukkit.getServer().unloadWorld(w, false)){
                System.out.print("<--------------- UNLOADED");
            } else {
                System.out.print("<--------------- ERROR");
            }
 
            WorldCreator wr = new WorldCreator(name);
           
            wr.copy(w);
            wr.environment(Environment.NORMAL);
           
            File folder = w.getWorldFolder();
            if(!folder.isDirectory()) return;
                for(File file : folder.listFiles()) {
                    file.delete();
                }
            folder.delete();
           
           
            wr.createWorld();

Firt time: All OK
Second/Third etc time:
"<--------------- ERROR"

Code:

Please, help me :/

 

Here is a small example, how to delete and copy a WorldBackup.

Code:

    public void resetMap(World resetWorld) {
        //teleport all players in the world
        for(Player p : resetWorld.getPlayers()) {
            p.teleport(Bukkit.getServer().getWorlds().get(0).getSpawnLocation());
        }
        
        //unload the map
        Bukkit.getServer().unloadWorld(Bukkit.getServer().getWorld(resetWorld.getName()), false);
        
        //copy the map
        try {
            File normal = new File(resetWorld.getName());
            File backup = new File("plugins" + File.separator + "backup" + File.separator + resetMap);
            if(normal.exists() && backup.exists()) {
                FileUtils.forceDelete(normal); 
                FileUtils.copyDirectory(backup, new File(resetWorld.getName()));
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        
        //load the map 
        Bukkit.getServer().createWorld(new WorldCreator(resetWorld.getName()));
    }

 

All are working but only one time!
Why?

PS: I use Java 7

edit:
The resetMap-Method is my own, you can rename the method if you want
