VaultAPI - Abstraction Library API for Bukkit Plugins

How to use with maven: note that the VaultAPI version is 2 numerals, unlike Vault versions which are 3. The 2 numerals in the VaultAPI will always correspond to the 2 beginning numerals in a Vault version to make it clear what versions your plugin will for sure work with.

Why Vault?

I have no preference which library suits your plugin and development efforts best. Really, I thought a central suite (rather...Vault) of solutions was the the proper avenue than focusing on a single category of plugin. That's where the idea for Vault came into play.

So, what features do I think you'll like the most?

• No need to include my source code in your plugin
• Broad range of supported plugins
• Choice!

Building

VaultAPI comes with all libraries needed to build from the current branch.

Implementing Vault

Implementing Vault is quite simple. It requires getting the Economy, Permission, or Chat service from the Bukkit ServiceManager. See the example below:

package com.example.plugin;

import java.util.logging.Logger;

import net.milkbowl.vault.chat.Chat;
import net.milkbowl.vault.economy.Economy;
import net.milkbowl.vault.economy.EconomyResponse;
import net.milkbowl.vault.permission.Permission;

import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.RegisteredServiceProvider;
import org.bukkit.plugin.java.JavaPlugin;

public class ExamplePlugin extends JavaPlugin {
    
    private static final Logger log = Logger.getLogger("Minecraft");
    public static Economy econ = null;
    public static Permission perms = null;
    public static Chat chat = null;

    @Override
    public void onDisable() {
        log.info(String.format("[%s] Disabled Version %s", getDescription().getName(), getDescription().getVersion()));
    }

    @Override
    public void onEnable() {
        if (!setupEconomy() ) {
            log.severe(String.format("[%s] - Disabled due to no Vault dependency found!", getDescription().getName()));
            getServer().getPluginManager().disablePlugin(this);
            return;
        }
        setupPermissions();
        setupChat();
    }
    
    private boolean setupEconomy() {
        if (getServer().getPluginManager().getPlugin("Vault") == null) {
            return false;
        }
        RegisteredServiceProvider<Economy> rsp = getServer().getServicesManager().getRegistration(Economy.class);
        if (rsp == null) {
            return false;
        }
        econ = rsp.getProvider();
        return econ != null;
    }
    
    private boolean setupChat() {
        RegisteredServiceProvider<Chat> rsp = getServer().getServicesManager().getRegistration(Chat.class);
        chat = rsp.getProvider();
        return chat != null;
    }
    
    private boolean setupPermissions() {
        RegisteredServiceProvider<Permission> rsp = getServer().getServicesManager().getRegistration(Permission.class);
        perms = rsp.getProvider();
        return perms != null;
    }
    
    public boolean onCommand(CommandSender sender, Command command, String commandLabel, String[] args) {
        if(!(sender instanceof Player)) {
            log.info("Only players are supported for this Example Plugin, but you should not do this!!!");
            return true;
        }
        
        Player player = (Player) sender;
        
        if(command.getLabel().equals("test-economy")) {
            // Lets give the player 1.05 currency (note that SOME economic plugins require rounding!)
            sender.sendMessage(String.format("You have %s", econ.format(econ.getBalance(player.getName()))));
            EconomyResponse r = econ.depositPlayer(player, 1.05);
            if(r.transactionSuccess()) {
                sender.sendMessage(String.format("You were given %s and now have %s", econ.format(r.amount), econ.format(r.balance)));
            } else {
                sender.sendMessage(String.format("An error occured: %s", r.errorMessage));
            }
            return true;
        } else if(command.getLabel().equals("test-permission")) {
            // Lets test if user has the node "example.plugin.awesome" to determine if they are awesome or just suck
            if(perms.has(player, "example.plugin.awesome")) {
                sender.sendMessage("You are awesome!");
            } else {
                sender.sendMessage("You suck!");
            }
            return true;
        } else {
            return false;
        }
    }
}
