Plugin Help Values don't get saved in config.yml file

Hey guys,
I wanted to write a plugin, thats takes my position when I type the command and writes the value of if to the config.yml file, but that doesn't work. I made a second command to write the Location into the config.yml file, that works, I can also access that value, but when I reload the server, the config file is empty, also when I open the config file in my plugin, the file is empty.
Here's my code of the command which should write the x-position of the player to the config:

Code:

@Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        if(label.equalsIgnoreCase("config")){
            this.getConfig().addDefault("Config.x1", Manager.getLocation1().getX());
            int configx = this.getConfig().getInt("Config.x1");
           
            sender.sendMessage("config: " + configx);
           
            return true;
        }

Here my loadConfig method:

Code:

    public void loadConfig(){
        getConfig().options().copyDefaults(true);
        saveConfig();
       
    }

Hope you could help me, thank you

 

Please don't mark this as 'Plugin Help', mark it as 'Plugin Development' and to get a quick response, move this to the 'Plugin Development' thread.

And why didn't you put your "loadConfig" method in your onEnable? When the plugin enables, so should the config.
