Mojang finally reveals Minecraft: Java Edition’s entire codebase after 16 years to help modders build and improve mods faster

Mojang notes it has already reduced some obfuscation in past updates (starting around 2019), but now plans a complete removal starting with the first snapshot released after Mounts of Mayhem. While the transition could disrupt some existing modding tools, the team says it will help modders adapt.

The studio acknowledges that tools built for obfuscated code may face challenges and intends to offer support so creators have time to prepare.

To ease the shift, Mojang will publish un-obfuscated “experimental release” builds alongside the obfuscated versions beginning with the next snapshot. Modders can use these experimental builds to test and update their tooling and workflows before the full transition.

Why remove obfuscation? Mojang says the answer is straightforward: modding is central to Java Edition, and obfuscation makes it harder. Removing it should speed up development, simplify maintenance, and reduce the need to decipher unclear names and tangled code.

Mojang adds that debugging should become simpler and crash reports far more readable once obfuscation is removed.

The developer also clarifies this change does not alter the current EULA — so modders and creators can continue their work under the same terms.

Minecraft creator weighs in on the Creeper debate sparked by Mojang CCO’s recent comments, says he “tried to fix” it years ago because it was “anti-fun”
