Known issues & safety notes

How to set up SpongeVanilla 26.2 Snapshot 4

  1. Install Java 25 or newer (e.g. Eclipse Temurin) and check it with java -version.
  2. Download the SpongeVanilla jar 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 — SpongeVanilla 26.2-snapshot-4
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 25 ] 2>/dev/null; then
  echo "Java 25 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?
