Updating netty manually for Minecraft 1.12

Get your minecraft_server.1.12.2.jar from the root of your server, download the last bundled jetty 4.1 version https://repo1.maven.org/maven2/io/netty/netty-all/4.1.68.Final/netty-all-4.1.68.Final.jar

Open your server jar with 7zip and navigate to minecraft_server.1.12.2.jar\io\netty\

open the netty jar file you downloaded and go to netty-all-4.1.68.Final.jar\io\netty\

back in the minecraft server jar delete these 6 folders

now simple copy the same 6 folders from the netty package into the minecraft jar

throw the jar back into the root of your server and you are done!

this is for Forge or Vanilla

The link with the netty download does not work for me. It takes me to a blank page which only says "Forbidden".

Is there any other link I can use to get the right netty version. I tried downloading it from https://github.com/netty/netty/releases/tag/netty-4.1.37.Final but there I was not able to locate the right file I needed.

hello! when I enter the netty file I do not get the 6 files to replace

For anyone struggling to find the jar folder, the latest versions do not have it for some reason... If you grab 4.1.27 on https://javalibs.com/artifact/io.netty/netty-all, you can follow the steps normally; if you don't want that old of a version, you can go up to v68 before the jar portion disappears

Does anyone know how to find the files required now?

@Spreewald1 I love link rot :D
I found a link to a maven repo that has those exact files you need (from my old 4.1.27 comment) here: https://repo1.maven.org/maven2/io/netty/netty-all/4.1.27.Final/

Download netty-all-4.1.27.Final.jar and follow the instructions as normal; I verified they are the complete same with file sizes and last modification date

@PillowOfBricks Thank you so much for responding, especially on a post that’s 2 years old. 🤣

Updated the gist, thanks for the heads up!
