ShulkerVacuum

Vacuum and Trash shulker boxes, now for Minecraft 1.17 to 26.3 on Spigot, Paper and Purpur.

New in 2.1

• One jar runs on every version from 1.17 to 26.3 (Java 16 or newer, whatever your server already uses).
• Works on Spigot as well as Paper and Purpur.
• Custom textures (via the included resource pack) on 1.21.4 and newer; older versions show the normal shulker box look.

Features

• Shulker Box of Vacuum (any shulker box + hopper): off-hand stores blocks you mine, main hand stores items you pick up. A full box hands extras to your inventory.
• Shulker Box of Trash (any shulker box + lava bucket): off-hand deletes blocks you mine, main hand deletes items you pick up.
• Any colour of shulker box works, and crafting keeps the box's colour and contents.
• Shulker boxes are never stored or deleted, and breaking chests or other containers is left alone.
• Boxes from earlier versions keep working.

Marked beta: it's built and compile-checked against the 1.17 and 26.3 APIs, but hasn't been play-tested on every version in between. Test on a copy of your world first, and report problems on GitHub.
