Use /ah to open the auction house. 

Requirements:

• Vault: https://www.spigotmc.org/resources/vault.34315/
• Any Ecomony Plugin (for example Essentials or BetterEconomy)

Admins on the server can also use /ah admin [opens the ah, but if you click on an item you can delete it from the ah] /ah ban [make a player unable to use /ah]

For the commands a description is provided in-game. If you aren't op on the server and want to use permissions to access these commands, the current permission is called "auctionhouse.moderator"

Q&A

Q: Can I customize messages and GUI texts? A: Yes, edit the messages.yml file in the plugin folder. You can change the currency from "coins" to whatever you like under "placeholders" in the messages.yml file.

Q: How do I update the config with new options? A: The plugin automatically adds missing config options when updated, without overwriting your custom settings.

Q: How do I spawn that Auction Master Villager and the item displays and how do I remove them? A: If you are op, then you can do /ah summon <entity> which you can tab-complete. To remove them, simply punch them while being in creative mode and being op on the server.

Q: The Auction Master Villager and the item displays disappear after a while A: If you do something like /kill @e, of course they will be removed. Also, if you use /teleport @e, they will be moved.

Q: How do I report bugs or request features? A: You can join my new discord server and contact me directly.
