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 25w14craftmine

  1. Install Java 21 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.

Linux / macOS — start.sh

#!/bin/sh
# start.sh — Minecraft 25w14craftmine
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 21 ] 2>/dev/null; then
  echo "Java 21 or newer is required (found Java $JAVA_MAJOR)."
  exit 1

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?

Upgrading

FAQ

What Java version does Minecraft 25w14craftmine need?

Minecraft 25w14craftmine needs Java 21 or newer. Running it on an older Java fails with an UnsupportedClassVersionError mentioning class file version 65.0.

Is Minecraft 25w14craftmine safe for my survival world?

Only on a copy. Preview versions are experimental and upgrade worlds irreversibly; keep a backup and don't switch a live world to a snapshot, pre-release or release candidate.

Is this the Minecraft game or an APK?

No. This is the Java Edition dedicated server — software for hosting a world. It is not the game client and there is no Android APK. Phone and console players use Bedrock Edition.
