How to not make new config when there is already one

Now this worked before. My thing did not generate a new config or anything but it does now and it just keeps replacing the old one. Help, how can I make it so that if there is a config it wont make a new one?!
my loadconfig method(THIS WORKED BEFORE):

Code:

 public void loadConfig(){
      getConfig().options().copyDefaults(true);
      saveConfig();
List<String> players = new ArrayList<String>();
    for (Player player : Bukkit.getOnlinePlayers()) {
      players.add(player.getName());
      String name = player.getName();
      if (!getConfig().contains(name)) {
        getConfig().set(name, Integer.valueOf(0));
        credits.put(name, Integer.valueOf(getConfig().getInt(name)));
        saveConfig();
      } else {
        credits.put(name, Integer.valueOf(getConfig().getInt(name)));
        saveConfig();
      }
      if (!getConfig().contains(name + "boughtsoldier")) {
        getConfig().set(name + "boughtsoldier", Boolean.valueOf(true));
        boughtsoldier.put(name, Boolean.valueOf(getConfig().getBoolean(name + "boughtsoldier")));
        saveConfig();
      } else {
        boughtsoldier.put(name, Boolean.valueOf(getConfig().getBoolean(name + "boughtsoldier")));
        saveConfig();
      }
      if (!getConfig().contains(name + "boughtstandard")) {
        getConfig().set(name + "boughtstandard", Boolean.valueOf(true));
        boughtstandard.put(name, Boolean.valueOf(getConfig().getBoolean(name + "boughtstandard")));
        saveConfig();

        saveConfig();
      }
    }
    saveConfig();
  }

and in the onEnable it says loadconfig(); then saveconfig();.

 

Java files have a built in method to see if they exist


if(someFile.exists()){


} else {
// load file here, create defaults, etc
}

 

I can't do that with getConfig()

 

Check out the implementation subheadings in this part of Bukkit's config API reference.

 

I dont know which part is wrong that deletes the config but it is in onEnable because when i open the server the plugin just deletes the config and makes a new one. here's my onEnable:

Code:

 public void onEnable() {
    getLogger().info("OMGPvP by william9518 is now enabled");
    PluginManager manager = getServer().getPluginManager();
    manager.registerEvents(new OMGPvPEventListener(this), this);
    getCommand("shop").setExecutor(new OMGPvPCommandExecutor(this));
    getCommand("credit").setExecutor(new OMGPvPCommandExecutor(this));
    getCommand("buy").setExecutor(new OMGPvPCommandExecutor(this));
    getCommand("faq").setExecutor(new OMGPvPCommandExecutor(this));
    getCommand("hg").setExecutor(new OMGPvPCommandExecutor(this));
    getCommand("givekit").setExecutor(new OMGPvPKitCommandExecutor(this));
    getCommand("givehead").setExecutor(new OMGPvPCommandExecutor(this));
    mainDirectory = getDataFolder().getPath();
    config = new File(mainDirectory + "/config.yml");
    if(!config.exists()){
        loadConfig();
        saveConfig();
    } else {
        saveConfig();
    }
  }

 

Use defaults instead of checking if they exist. It will do it for you.

You can either set the defaults in your onEnable method, or you can load a file as a default (which is much easier to do, ill show you how to do that)

Make a file next to your plugin.yml called "defaultConfig.yml" (or whatever you wish to name it, the name doesnt matter)

Write it like a standard YML file, with all of the default configuration items inside of it.

Then do this, on enable (before loading your preferences)

Code:

Configuration defaultConfig = YamlConfiguration.loadConfiguration(getResource("defaultConfig.yml"));
getConfig.setDefaults(defaultConfig);
getConfig().options().copyDefaults(true);
saveConfig();

 

Didnt work!

 

Why are you going in such a round about way to set defaults.

 

How would you do it?

 

If you want to write the entire file into the 'data folder' saveResource method is a much better alternative.
