Saving itemstacks to a config

My config keeps saying that a section I created is not a list. plugin.customConfig is the same as plugin.getConfig its just so I can name the yml file something else than config.

*EDIT*
It is about in the middle of the code and it says if (plugin.customConfig.isList... Before the suppress warnings and after p.sendMessage("debug-1") but before the other debug messages.
That returns false for some reason. I don't know how to define it as a list and there are no good config tutorials that teach this.

Code:

public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args)
    {
        if (commandLabel.equalsIgnoreCase("makechest"))
        {
            if (sender instanceof Player)
            {
                Player p = (Player) sender;
                if (args.length == 3)
                {
                    String name = args[0];
                    String option = args[1];
                    double percentage = Double.parseDouble(args[2]);
              
                    if (plugin.customConfig.getConfigurationSection(name) == null)
                    {
                        plugin.customConfig.createSection(name);
                    }
                    ConfigurationSection path = plugin.customConfig.getConfigurationSection(name);
                    if (path.getConfigurationSection(option) == null)
                    {
                        path.createSection(option);
                        plugin.customConfig.addDefault(name + "." + option + ".Percentage", percentage);
                        plugin.customConfig.createSection(name + "." + option + ".Items");
                        plugin.customConfig.options().copyDefaults(true);
                        try {
                            plugin.customConfig.save(plugin.customConfigFile);
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                        ItemStack[] items = p.getInventory().getContents();
                        p.sendMessage("debug-1");
                     
                        if (plugin.customConfig.isList(name + "." + option + ".Items"))
                        {
                            @SuppressWarnings("unchecked")
                            List<ItemStack> list = (List<ItemStack>) plugin.customConfig.getList(name + "." + option + ".Items");
                            p.sendMessage("debug");
                            for (ItemStack item : items)
                            {
                                p.sendMessage("debug1");
                                if (item != null && item.getType() != null)
                                {
                                    p.sendMessage("debug2");
                                    list.clear();
                                    list.add(item);
                                }
                                plugin.customConfig.set(name + "." + option + ".Items", list);
                                plugin.customConfig.options().copyDefaults(true);
                                try {
                                    plugin.customConfig.save(plugin.customConfigFile);
                                } catch (IOException e) {
                                    e.printStackTrace();
                                }
                            }
                            p.sendMessage(ChatColor.GREEN + "Option: " + option + " for chest: " + name + " with percentage: " + percentage + " has been created!");
                        }
                    } else {
                        p.sendMessage(ChatColor.RED + "That option already exists!");
                        return false;
                    }
                } else {
                    p.sendMessage(ChatColor.RED + "Correct Usage: /makechest <name> <option> <percentage>");
                    p.sendMessage(ChatColor.RED + "Example Usage: /makechest donator Option1 100");
                    return false;
                }
            }
        }
        return false;
    }

 

You're trying to create a section,

Code:

plugin.customConfig.createSection(name + "." + option + ".Items");

then check if it's a list, two different things. Also, inside the if statement, on this line,

Code:

List<ItemStack> list = (List<ItemStack>) plugin.customConfig.getList(name + "." + option + ".Items");

won't work, because configuration lists only store values, like a string; they don't store configuration sections, which is what an itemstack would turn into. I don't know if you've looked through the wiki article on configs yet, but this might help.

 

@techboy291 Thanks for helping. Do you know how I would be able to store itemstacks or inventories?

 

@ClassifiedLife google it it has been around a. Lot! I'm sure you will find the answer

 

config.set("Path", itemstack.serialize());
