ShopPlugin

ShopPlugin lets players create chest-based shops with signs in Minecraft. Only the shop owner can edit the sign, open the chest, or destroy either, while others can buy items by right-clicking the sign. Supports Vault for economy or works without it.
Supported Version: Minecraft 1.21.8 (Paper).
Dependencies (economy version): Vault, economy plugin (e.g., EssentialsX).
Usage:

Create a Shop:

1. Place a chest with items (e.g., 5 diamonds).
   Add a sign nearby:

2. With economy: [Shop], DIAMOND, 5, 100$
   Without economy: [Shop], DIAMOND, 5

3. The sign-placer becomes the owner.

4. Buying: Non-owners right-click the sign to buy items (if funds/items available).
   Owner Privileges: Only the owner can edit the sign, open the chest, or destroy them.
   Installation: Place ShopPlugin-1.0-SNAPSHOT.jar in plugins, add Vault/EssentialsX (if using . economy), and restart.
