Effect Shop

EffectShop 2.0.0 — Full Rewrite

The plugin has been completely rewritten. One jar now supports Minecraft 1.16.5 through 26.3 on Spigot, Paper, Purpur, Folia (and other Bukkit-based forks). Java 17+ required.

Breaking changes

• The command is now /effectshop (the old /eshop has been removed)
• New config.yml format (v2) — your old config is automatically backed up to config-v1-backup.yml and ported prices must be moved over

New

• Fully config-driven menus: slots, sizes, materials, icons, lore, prices, durations, fill/accent panes, header and back items — everything editable, unlimited categories
• Stack modes for buying an already-active effect: REPLACE (restart), ADD (extend duration), MAX (refund-free refusal while the remaining time is longer)
• Sound feedback (open / navigate / purchase / denied), configurable resource keys
• MiniMessage support (<gold>, <bold>, ...) alongside legacy & codes
• Real potion items: the Invisibility icon looks like an actual potion
• Close button in the main menu; staying in the menu after a purchase with live balance update
• /effectshop reload — hot-reload the configuration (no restart)
• /effectshop test — builds all menus headlessly (handy for setup and CI checks)
• Attributes / "No Effects" lines are hidden from item tooltips on every version (data components on 1.21.5+, item flags on older servers)

Fixes and hardening

• Fixed the balance line rendering a literal %player_level% placeholder in the main menu
• Items can no longer be moved into/out of the shop via drag or shift-click
• Purchases are race-safe and verified against the live XP level

Compatibility

• Runtime capability detection instead of hardcoded versions: Adventure components, registries, data components and potion APIs all have legacy fallbacks
• Folia support via the entity scheduler (folia-supported: true)
• Verified on: Paper 1.16.5 / 1.21.11 / 26.1.2 / 26.2 / 26.3, Spigot 1.21.1, Folia 1.21.11
