Requirements

  • Paper 1.21+ or Folia 1.21+
  • Java 21
  • PacketEvents — required for vendor NPCs
  • One of: Vault + EssentialsX, GemsEconomy, CoinsEngine, or PlayerPoints

Installation

  1. Drop the JAR into your plugins/ folder
  2. Install PacketEvents if you haven't already
  3. Start the server — a default config will generate
  4. Run /traders in-game to get started

See docs/installation.md for a full setup walkthrough.

Building

# Clone the repo
git clone https://github.com/JimSpecter/SovereignTraders.git
cd SovereignTraders
# Build (obfuscated with ProGuard)
./gradlew buildFree
# Development build (unobfuscated)
./gradlew shadowFreeJar
# Spin up a local test server
./gradlew runServerFree

The test server task downloads Paper automatically and pre-installs VaultUnlocked, EssentialsX, and PacketEvents. Drop any additional plugin JARs (Citizens.jar, GemsEconomy.jar, etc.) in the project root and they'll be picked up automatically.

NPC shop plugin for Paper 1.21+
VersionJavaPaperFoliaLicense
Create shops, attach them to NPC vendors, and let players buy, sell, or barter — all through a clean in-game GUI with no YAML editing required.
Features
FeatureDescription
Custom NPC vendorsSpawn vendors with custom skins, holograms, and equipment. No Citizens dependency, but it's supported.
Three trade modesBuy, sell, and item-for-item barter — all configurable per listing.
Multi-economyWorks with Vault, GemsEconomy, CoinsEngine, and PlayerPoints out of the box.
In-game editorCreate and manage catalogs, listings, and vendors entirely in-game.
QuotasLimit how many times a player can buy an item, with optional auto-reset timers.
Sales & discountsApply discounts to individual items or entire catalogs, with time-window scheduling.
DirectivesRun console or player commands when a player completes a purchase (ranks, kits, crate keys, etc.).
Barter modeAccept items instead of currency — define exactly what to take and what to give.
Bulk buy/sellShift-click for a quantity selector with smart presets.
Transaction logEvery buy, sell, and barter is written to a plain-text log for auditing.
Folia supportThread-safe and Folia-compatible out of the box.
Citizens integrationLink vendors to Citizens NPCs if you prefer.
dtlTraders migrationOne-click import from dtlTraders and dtlTradersPlus.
Requirements
  • Paper 1.21+ or Folia 1.21+
  • Java 21
  • PacketEvents — required for vendor NPCs
  • One of: Vault + EssentialsX, GemsEconomy, CoinsEngine, or PlayerPoints
Installation
  1. Drop the JAR into your plugins/ folder
  2. Install PacketEvents if you haven't already
  3. Start the server — a default config will generate
  4. Run /traders in-game to get started
See docs/installation.md for a full setup walkthrough.
Building
# Clone the repo
git clone https://github.com/JimSpecter/SovereignTraders.git
cd SovereignTraders
# Build (obfuscated with ProGuard)
./gradlew buildFree
# Development build (unobfuscated)
./gradlew shadowFreeJar
# Spin up a local test server
./gradlew runServerFree
The test server task downloads Paper automatically and pre-installs VaultUnlocked, EssentialsX, and PacketEvents. Drop any additional plugin JARs (Citizens.jar, GemsEconomy.jar, etc.) in the project root and they'll be picked up automatically.
