Nexo Integration

Nexo is optional (softdepend). Without Nexo the market works with normal Minecraft items.

Installation (admin)

1. Install Nexo and its resource pack per Nexo documentation.
2. Leave GrzybcioRynek-1.0.3.jar in plugins/ (softdepend will load Nexo earlier if present).
3. Restart Paper 26.2.
4. In the log look for: Wykryto Nexo! Włączono wsparcie dla niestandardowych przedmiotów.

If Nexo is present but the API fails to load, a warning appears in the log — the market still works, without Nexo IDs.

Test

1. Take a Nexo item in hand.
2. /wystaw 50 (or /market sell 50).
3. /market admin inspect <id> — the Nexo line should not be empty.
4. Buy the listing with a second player — the item should return with enchants / meta as at listing time.

What you need to know as an admin

• The plugin stores the listing's entire ItemStack plus the Nexo ID as a safeguard.
• When returning the item it uses the saved stack first; rebuild from the pack only when the saved item is damaged (AIR).
• After changing or removing an ID in the Nexo pack, old listings may still work on the saved stack — or fail if the stack is AIR and the ID no longer exists. Details: Custom Items → Nexo, Troubleshooting.
