Solved Multiple config files- IllegalArgumentException: File cannot be null

I've been trying to educate myself on working with multiple config files. I want to save an array of all jails for my viewing to help administrate staff decisions. I wanted this to be on a new file, and now get an IllegalArgumentException. Here's the starting code where I make the file called jails:

Code:

public class Intergrat extends JavaPlugin{
    File jails;
    FileConfiguration config = this.getConfig();
   
    public Permission sSpawn = new Permission("Intergrat.sSpawn");
    public Permission spawn = new Permission("Intergrat.spawn");
    public Permission tSpawn = new Permission("Intergrat.tSpawn");
    public Permission home = new Permission("Intergrat.home");
    public Permission tHome = new Permission("Intergrat.tHome");
    public Permission freeze = new Permission("Intergrat.freeze");
    public Permission jail = new Permission("Intergrat.jail");
   
    public void onEnable(){
        config.addDefault("Spawn.Exists", false);
        config.addDefault("Jail.Exists", false);
        config.options().copyDefaults(true);
        this.saveConfig();
        jails = new File(this.getDataFolder(), "jails.yml");
        if(!jails.exists()){
            try{
                jails.createNewFile();
            }catch(IOException e){
                Bukkit.getServer().getLogger().severe("Unable to create jails.yml");
            }
        }
        Bukkit.getServer().getLogger().info("Intergrat by SeductiveWalrus has been enabled");
    }
   
    public void onDisable(){
        Bukkit.getServer().getLogger().info("Intergrat has been disabled");
    }
   
    FileConfiguration jfile = YamlConfiguration.loadConfiguration(jails);
   
    public void saveJails(){
        try{
            jfile.save(jails);
        }catch(IOException e){
            Bukkit.getServer().getLogger().severe("Unable to save jails.yml");
        }
    }

Now here's the only command I use it in:

Code:

else if(cmd.getName().equalsIgnoreCase("jail")){
       if(s instanceof Player){
         Player p = (Player) s;
         if(p.hasPermission(jail)){
           if(args.length > 0){
             Player t = Bukkit.getPlayerExact(args[0]);
             if(t != null && !t.hasPermission(jail)){
               if(config.getBoolean("Jail.Exists") == true){
                 if(config.getBoolean("Players." + t.getUniqueId() + ".Jailed") == true){
                   config.set("Players." + t.getUniqueId() + ".Jailed", false);
                   saveConfig();
                   p.sendMessage(ChatColor.GRAY + t.getName() + " has been unjailed");
                   t.sendMessage(ChatColor.GRAY + "You have been unjailed");
                   if(config.getBoolean("Players." + t.getUniqueId() + ".Home.Exists") == true){
                     World hw = Bukkit.getServer().getWorld(config.getString("Players." + t.getUniqueId() + ".Home.World"));
                     double hx = config.getDouble("Players." + t.getUniqueId() + ".Home.X");
                     double hy = config.getDouble("Players." + t.getUniqueId() + ".Home.Y");
                     double hz = config.getDouble("Players." + t.getUniqueId() + ".Home.Z");
                     t.teleport(new Location(hw, hx, hy, hz));
                   }else if(config.getBoolean("Spawn.Exists") == true){
                     World sw = Bukkit.getServer().getWorld(config.getString("Spawn.World"));
                     double sx = config.getDouble("Spawn.X");
                     double sy = config.getDouble("Spawn.Y");
                     double sz = config.getDouble("Spawn.Z");
                     t.teleport(new Location(sw, sx, sy, sz));
                   }else t.damage(t.getMaxHealth());
                 }else{
                   if(args.length > 1){

I'd really appreciate any help on this, as I've had a hard time educating myself on this. I don't want to be spoonfed the fix for this, I just want to know where I went wrong so I can teach this to myself. I still consider myself a beginner, so any help would be strongly appreciated. Thanks guys.

There's something wrong with your plugin.yml, can we see it?

 

That's the wrong issue .

@gamingmind99

When does this error occur? Is jail.yml being created?

EDIT: Can you show line 54 from Intregat.java

 

@gamingmind99 Create a file 'config.yml' in your project

 

Are you using 1 class? I suggest using PasteBin as it helps everyone read your code instead of separating it in half

 

@CeramicTitan when I get home from school I'll label it and make pastebins for everything.

 

@YoloSanta @CeramicTitan

Plugin main class(only class till I get around to making a listener) code: https://pastebin.com/8e8P2Kjs
Error: https://pastebin.com/xA5rFrwS

Thanks guys. Sorry for delay, didn't have time yesterday

 

Take a look at this example, where I used YamlConfiguration; https://github.com/CeramicTitan/IsP...e/ceramictitan/playeronline/PlayerOnline.java

 

@CeramicTitan thank you
