Minecraft Snapshot 22w13a Server Jar Download

Version facts

What changed

Newest upstream commits:

• #1 · 31 Mar 2022 Added Allay mob
• Added Ancient Cities
• Allays will collect all the surrounding items that match the item they are holding
• Allays will like a player who hands them an item and will bring the items they collect to their liked player
• If the Allay hears a noteblock play, that noteblock becomes the Allay's favorite noteblock for 30 seconds. The Allay will stay near that noteblock for that duration and bring its collected items to the noteblock instead of to the player

Compatibility

No plugins or mods — the unmodified game exactly as Mojang ships it (data packs still work).

Players need a Minecraft: Java Edition Snapshot 22w13a client on the same version.

Known issues & safety notes

• Preview builds are experimental: they can corrupt or irreversibly upgrade worlds, and most plugins and mods do not support them yet. Test on a copy of your world.

How to set up Minecraft Snapshot 22w13a

1. Install Java 17 or newer (e.g. Eclipse Temurin) and check it with java -version.
2. Download server.jar from Mojang (button above) into an empty folder.
3. Start it once with the script below; it creates eula.txt and stops.
4. Set eula=true in eula.txt to accept the Minecraft EULA, then start again. Players join on port 25565.

#!/bin/sh
# start.sh — Minecraft 22w13a
cd "$(dirname "$0")"
JAVA_MAJOR=$(java -version 2>&1 | awk -F'"' '/version/ {split($2, v, "."); print (v[1] == "1") ? v[2] : v[1]}')
if [ "$JAVA_MAJOR" -lt 17 ] 2>/dev/null; then
  echo "Java 17 or newer is required (found Java $JAVA_MAJOR)."
  exit 1
fi
java -Xms4G -Xmx4G -jar server.jar nogui

@echo off
REM start.bat — Minecraft 22w13a
REM Needs Java 17 or newer: run "java -version" to check.
java -Xms4G -Xmx4G -jar server.jar nogui
pause

Rule of thumb: 2–4 GB for a few friends, 6–10 GB for a public server with plugins. Set -Xms equal to -Xmx and leave 1–1.5 GB for the operating system. How much RAM?

Docker

docker run -d -p 25565:25565 -e EULA=TRUE -e TYPE=VANILLA -e VERSION=22w13a --name mc itzg/minecraft-server

Uses the community itzg/minecraft-server image, which downloads the file itself.
