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 the vanilla 1.17 server Mojang says to add -Dlog4j2.formatMsgNoLookups=true to the Java start command (Mojang advisory).
  • Known issues: search Quilt's issue tracker for 1.17-pre3

How to set up Quilt 1.17 Pre-Release 3

  1. Install Java 16 or newer (e.g. Eclipse Temurin) and check it with java -version.
  2. Download the official Quilt installer (quilt-installer-0.15.1.jar) above.
  3. In an empty folder run: java -jar quilt-installer-0.15.1.jar install server 1.17-pre3 --download-server --create-scripts --install-dir=server
  4. The installer downloads the vanilla 1.17 Pre-Release 3 server, sets up Quilt Loader and writes start scripts into server/. Start it once, then accept the EULA in eula.txt.
  5. Put Quilt (and most Fabric) mods into server/mods/.

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?
