How to reload config.yml file on command in Bukkit Plugin?

I was trying to reload config.yml file on command with Bukkit Plugin, I don't know how to do it.

I searched on google and I found one answer, but when I used it, config.yml was not generating. Here's my code:

First you need to remove the final modifier from your config variables, else this can't refresh from config file.

Then you need a method for reload the config and set the config variables again. An example based on your code:

@Override
public void onEnable() {

    loadConfig(this);
}

private final String prefix = ChatColor.AQUA + "[";

private String prefixTrue;
private String prefixFalse;

public void loadConfig(Plugin plugin) {
    File file = new File(plugin.getDataFolder().getAbsolutePath() + "/config.yml");
    FileConfiguration cfg = YamlConfiguration.loadConfiguration(file);
    prefixTrue = prefix + cfg.getString("prefix") + "]" + ChatColor.GREEN + " ";
    prefixFalse = prefix + cfg.getString("prefix") + "]" + ChatColor.RED + " ";
}

Make sure that you call the method loadConfig in onEnable and every time you want to reload the config
