Paper on 1.17.1: common questions
Does Paper support Minecraft 1.17.1?
Yes. 200 builds have been published for 1.17.1, the newest being build 411. 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 Paper 1.17.1?
Java 16 or newer. The requirement comes from Minecraft 1.17.1 itself rather than from Paper, so it applies to any server software running this version. A newer Java than that is fine.
Which Paper build should I run on 1.17.1?
The newest one, build 411, published 4 y 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 Paper'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.
