Spigot on 1.21.9: common questions
Does Spigot support Minecraft 1.21.9?
Yes. 5 builds have been published for 1.21.9, the newest being build 4540. This is not a declared claim: each build below is a real file the project released for this version.
Which Java version do I need for Spigot 1.21.9?
Java 21 or newer. The requirement comes from Minecraft 1.21.9 itself rather than from Spigot, so it applies to any server software running this version. A newer Java than that is fine.
Which Spigot build should I run on 1.21.9?
The newest one, build 4540, published 10 mo ago. Later builds for the same Minecraft version are bug fixes and performance work, so there is rarely a reason to run an older one deliberately.
Is this download official?
Yes. Every link points at Spigot's own release or API. MCReference does not mirror, re-host or repackage a jar; where the project publishes a SHA-256 we show it so you can verify the file you got.
