[NEZNAMY]

Why does purpur 1.21.4 contain neoforge code? It is also trying to remap a module meant for MC 26.1. The one for 1.21.4 is fine and does not need remaping.

[fire7d]

I tested it on original Purpur 1.21.4 (without my change) and its still that way.

[NEZNAMY]

Turns out this affects all paper-based servers since 1.20.5, when remapping was introduced, until 1.21.4. This is because the remapping dependency only supports java versions up to 23 and I compiled v26_1 module with java 25. Turns out the module can be compiled with Java 21, the error I was getting when adding the module and used 25 turned out to be caused by something else, so I can change it to 21 like it is everywhere else.
Try new build from actions.

It's fixed now, thanks!
