Frequently asked

Does Project 4J work on Minecraft 1.21.11?

Yes. 1.21.11 is the newest Minecraft version Project 4J declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Which Minecraft versions does Project 4J support?

Everything the author has declared, from 1.21.1 up to 1.21.11. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install Project 4J on the client or the server?

Both. Every player needs it installed and so does the server, so anyone joining without it will be refused.

Which platform or loader does Project 4J support?

NeoForge. A build for one platform or loader will not necessarily load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for Project 4J?

On the newest Minecraft version it supports, Java 21 or newer. The requirement comes from the Minecraft version you run rather than from the modpack itself, so on an older supported Minecraft the answer is that version's Java, not this one.

What licence is Project 4J under?

Apache-2.0, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install Project 4J?

Use a launcher that imports packs, such as Prism Launcher, the Modrinth App or the CurseForge app, and open the pack file with it. The launcher installs the right loader and mods for you; installing a pack's mods by hand is the error-prone way.

Where do I download Project 4J safely?

Start with the author's page on Modrinth, which is where the data here is synced from. MCReference does not host or repackage files. The download link goes to the source recorded for that release; verify the publisher, filename and checksum before running it.
