Sponge on 1.21.11: common questions
Does Sponge support Minecraft 1.21.11?
Yes. 12 builds have been published for 1.21.11, the newest being build 12. 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 Sponge 1.21.11?
Java 21 or newer. The requirement comes from Minecraft 1.21.11 itself rather than from Sponge, so it applies to any server software running this version. A newer Java than that is fine.
Which Sponge build should I run on 1.21.11?
The newest one, build 12, published 2 h 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 Sponge'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.
