GlobalMarket is a global market system. It allows players to buy and sell items via a convenient in-game interface. It's similar WoW's Auction House or Runescape's Grand Exchange. I created this plugin awhile ago (back in the days of WebAuction, it's what inspired me) for private use, but I've decided to release it to the public. This plugin requires Vault and ProtocolLib, other than that, just drop it in plugins (make sure you have Vault plus a supported economy plugin installed) and start trading!

Features

Players can put any item up for sale using a dead simple in-game GUI system (see below)
Uses ProtocolLib for proper item serialization that supports Bukkit, Spigot, and Cauldron
Real time interface, all trades show up immediately without having to 'refresh' or close the GUI
No maintenance or admin interaction required
~~Mailbox system that allows you to set up market areas or auction houses~~ (not currently in 2.0.0)
~~A built in price guide that compiles average prices from previous transactions~~ (not currently in 2.0.0)

Usage

The Interface: This is a display of all current listings, you click an item to buy it. You can shift+click to remove a listing if you own it, or if you have the "globalmarket.listingsadmin" permission. Listings automatically expire after 1 week (configurable). You can use /market to access the menu.

Listings

Stock: When you purchase an item it will be sent to your stock. Stock is an entirely optional system but is suggested to be enabled, as disabling it will disable certain other features like /market send. The stock system can hold a configurable amount of stacks of items in a configurable amount of slots. Once you place an item in your stock, you can list it to be sold to other players. Players can also send items to other players' stock via /market send if they have the "globalmarket.command.send" permission.

Stock

Server Listings: You can create 'infinite listings' that do not expire and can't be bought out. Create them with /market createinf <price> <[amount]>. There's a dedicated section to server listings in the Market menu. You'll need the "globalmarket.command.createserverlisting" permission to do this. Or you can disable this system all-together in the config.

Commands

Command	Description	Permission
/market	Opens the Market menu.	globalmarket.use
/market ?	Shows command help.	<no permission>
/market send <player> <[amount]>	Sends the item you're holding to <player>'s stock. Amount is optional.	globalmarket.command.send
/market createinf <price> <[amount]>	Creates a server listing. Amount is optional.	globalmarket.command.createserverlisting
/market reload	Reloads config.yml	globalmarket.command.reload

Permissions

globalmarket.use - base permission, required to use /market
globalmarket.listingsadmin - ability to remove all listings
globalmarket.command.send - ability to use /market send
globalmarket.command.createserverlisting - ability to use /market createinf
globalmarket.command.reload - ability to use /market reload

Config

All config values have comments that explain what they do in config.yml, how convenient for me!
If you wish to blacklist items from being used on the Market, there is blacklist.json. You can add material values with meta values:

APPLE:0 - blacklist apples
INK_SAC:-1 - blacklist all dies

If you're running Cauldron, you can do things like:

oredict:ingotSteel - blacklist any item with an OreDictionary value matching ingotSteel
extracells:storage.component:-1 - blacklist all ExtraCells storage cells

Locale

Virtually every string in the plugin is editable via the "en_US.json" file, inside the plugin's JAR. It's pretty straightforward to edit. Don't replace or edit the %s or %1$s's, these are variables. For example, "Item sold: %s" would appear as "Item sold: Cobblestone" in-game. You can add/edit colors by typing & plus a color code. So light green (the color code is a) would be &a. You can find color codes here: http://ess.khhq.net/mc/

You can also create an entirely different language set, name it something like ch_CN.json, stick it in the server's JAR, and change the appropriate config value in config.yml to use it.
