Snapshot

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.
Log4Shell (CVE-2021-44228): for vanilla 1.7–1.11.2 Mojang says to download log4j2_17-111.xml into the server folder and add -Dlog4j.configurationFile=log4j2_17-111.xml to the start command (Mojang advisory).

How to set up Forge 1.7.10 Pre-Release 4

Install Java 8 or newer (e.g. Eclipse Temurin) and check it with java -version.
Download the official installer server.jar.zip into an empty folder.
Run java -jar server.jar.zip --installServer. It downloads the Minecraft server and libraries into the folder.
Start the server jar the installer created (forge-1.7.10-pre4-10.12.2.1149*.jar) with java -Xmx6G -jar <that file> nogui.
Accept Mojang's EULA in eula.txt (eula=true), start again, and put mods into mods/.
You can delete the installer and installer.log afterwards.

Modded servers need more memory: 6–8 GB for a light modpack, 8–12 GB or more for large packs. Leave 1–1.5 GB for the operating system. How much RAM?

Docker

docker run -d -p 25565:25565 -e EULA=TRUE -e TYPE=FORGE -e VERSION=1.7.10-pre4 --name mc itzg/minecraft-server

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

Upgrading

FAQ

What Java version does Forge 1.7.10 Pre-Release 4 need?

Forge 1.7.10 Pre-Release 4 needs Java 8 or newer. Running it on an older Java fails with an UnsupportedClassVersionError mentioning class file version 52.0.

Is Forge 1.7.10 Pre-Release 4 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 the Forge installer the server jar?

No. The installer (server.jar.zip) sets up the server: run it with --installServer, then start the server with the jar it creates.
