Files not being created

I'm trying to make a plugin that makes a file with a world name and .yml after it, but the file is never being created, here's the code:

Code:

public class WorldSpawn extends JavaPlugin implements Listener {
   
    WorldSpawn plugin;
    public static String pluginPrefix = (ChatColor.YELLOW + "[" + ChatColor.LIGHT_PURPLE + "WorldSpawn" + ChatColor.YELLOW + "] " + ChatColor.AQUA);
   
    public void onEnable() {
        if(!this.getDataFolder().exists()) { this.getDataFolder().mkdirs(); }
        getServer().getPluginManager().registerEvents(new Commands(this), this);
    }
   
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
        if(cmd.getName().equalsIgnoreCase("setspawn")) {
                Player p = (Player)sender;
                String worldName = p.getWorld().getName();
                File[] dirlist = getDataFolder().listFiles();
                  for(int i = 0; i < dirlist.length; i++) {
                    if(dirlist[i].isFile()) {
                    if(!dirlist[i].getName().matches(worldName + ".yml")) {
                      File world;
                      world = new File(plugin.getDataFolder(), (worldName + ".yml"));
                      if(!world.exists()) {
                         
                          double X = p.getLocation().getX();
                          double Y = p.getLocation().getY();
                          double Z = p.getLocation().getZ();
                          double YAW = p.getLocation().getYaw();
                          double PITCH = p.getLocation().getPitch();
                         
                          try {
                              world.createNewFile();
                              FileWriter fw = new FileWriter(world, true);
                              fw.write("# - " + worldName + " Spawn -\n");
                              fw.write("World: " + worldName + "/n");
                              fw.write("X: " + X + "/n");
                              fw.write("Y: " + Y + "/n");
                              fw.write("Z: " + Z + "/n");
                              fw.write("YAW: " + YAW + "/n");
                              fw.write("PITCH " + PITCH + "/n");
                              fw.close();
                             
                              p.sendMessage(pluginPrefix + ChatColor.GREEN + "Spawn has been set for " + ChatColor.AQUA + worldName);
                             
                              return true;
                          }catch(IOException z) {
                                z.getStackTrace();
                            }
                      }
                      }else {
                          p.sendMessage(pluginPrefix + ChatColor.RED + "Error: " + ChatColor.DARK_RED + "You cannot overwrite a previous set spawn, use /delspawn instead.");
                          return true;
                      }
                    }
                  }
                return false;
    }
}

Could it be that it's compiled under Java 7 not 6? Let me know what to do as soon as possible.

Hello xMakerx,
try make sure that the DataFolder exists, and try print out the boolean given by "File::createNewFile()";

 

MP5K Okay, I set it up so it outputs if the data folder exists and it gave me true, what should I try next?

MP5K
I got the problem fixed by adding a test file called "test.yml" but for some reason if I call plugin.getDataFolder() it returns null, how could that be?

mm.. that is weired. Do you have permission to write/read the folder?
