Been looking everywhere but no luck, got a custom Neoforge 1.20.1 modded server running on clients but on the server its giving me a crash I've never seen:

java.lang.ClassNotFoundException: org.apache.commons.codec.binary.Base64

attached will be the full log, like I said it runs fine for clients and I've seen SOME evidence that its the java version thats the culprit but for some reason Java 20 (the version I used to test this pack) isn't available as an option in bisect.

Java 20 is for 1.20.6+

Java 20 isn't available because Minecraft never used it.

#

Java 21 is for 1.20.6+.

That one^ sorry smoogiGiggle

#

1.20.1 uses java 17

hm alright, well then I'm wrong in that assumption my bad lol but this still happens with java 17

This looks like an incomplete Libraries folder

#

Definitely has nothing to do with the Java version and everything to do with a library Minecraft itself uses is missing. One of the Apache Commons libraries.

okay, I use prism launcher and found a libraries folder in there I can try finding what it needs maybe?

#

or just. copy the whole thing

Just copy the whole thing.

#

Should have been installed when you installed Forge...

#

yeah idk I ran it with neoforge blank and it was fine, added the mods and this happened

#

does look like I have some libraries the server doesnt, trying now

#

copied the whole libraries folder and its still happening

#

bizzare

Does it work if you remove valkyrienskies?

midnight trail
#

nope. gonna try removing some client side mods I may have accidentally left in

#

but ik removing Embeddium and Modernfix didnt help before

I know embeddium and valkyrienskies can cause issues together sometimes, but if removing that didnt work im not sure
