How come my kit pvp plugin doesn't work?

Here is my code (Don't steal it)

Code:java

package me.Ivan.Kits;
 
import java.io.File;
import java.io.IOException;
 
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.entity.Player;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Kits extends JavaPlugin{
 
    public void onEnable() {
        saveConfig();
        try {
            setupConfig(getConfig());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
 
    @SuppressWarnings("deprecation")
    public boolean onCommand(CommandSender sender, Command command,
            String commandLabel, String[] args) {
        if(commandLabel.equalsIgnoreCase("kits")) {
            if(sender instanceof Player){
                Player player = (Player) sender;
                if(args.length == 0) {
                    String[] classes = getConfig().getString("Kit.Names")
                            .split(",");
                    for(String s : classes){
                        if(s != null) {
                            player.sendMessage("[" + ChatColor.AQUA + s + ChatColor.WHITE + "] " + ChatColor.GRAY + ": " + ChatColor.DARK_GRAY + "You have gotten the " + s + "Kit! ");
                        }
                    }
                }else {
                    for(String s : getConfig().getConfigurationSection("Kits")
                            .getKeys(false)) {
                        if(args[0].equalsIgnoreCase("s")) {
                            player.getInventory().clear();
                            try {
                                String items = getConfig().getString(
                                        "Kits." + s + ".Items");
                                String[] indiItems = items.split(",");
 
                                for(String s1 : indiItems){
                                    String[] itemAmounts = s1.split("-");
                                    ItemStack item = new ItemStack(
                                            Integer.valueOf(itemAmounts[0]),

                                }
                                player.updateInventory();
                            } catch(Exception e) {
                                e.printStackTrace();
                            }
                        }
                    }
                }
            }
        }
        return false;
    }
 
    private void setupConfig(FileConfiguration config) throws IOException {
        if(!new File(getDataFolder(), "RESET.FILE").exists()){
            config.set("Kits.PvP.Items", "276-1,310-1,311-1,312-1,313-1,314-1,322:1-5");
 
            config.set("Kits.Names", "PvP");

    }
}
}
 

 

You shouldn't worry about people stealing it rather than you posted this in the wrong section.

It's supposed to go into "Plugin Development".

 

Moo-ved to correct section.
