For those who would find this useful I ended up asking about this problem in the mineos forum. have the latest java installed copy the universal JAR from libraries/net/minecraftforge/forge/1.18.1-39.0.5/ to your server directory add @user_jvm_args.txt @libraries/net/minecraftforge/forge/1.18.1-39.0.5/unix_args.txt to your additional java arguments box (copied out of the run.sh file) Mind you I'm using the mineos docker on my unraid server. So this was the solution for my particular docker. Ignore the jdk at the top its just a plugin the user who posted this was using to run multiple java versions on his docker.

I'm trying to make a 1.18.1 modded server on my unraid mineos docker and when I install the server pack it doesn't give me a runnable .jar to use. The only options I have to launch the server are a windows batch file "run" and .sh file under the name "run" which I can't use on my docker. With older versions of forge; 1.16.5 as an example; when installed, I'm given a .jar that I can use. But when I use the 1.18.1 forge installer I don't get one. Any help on this would be great since I've spent 2 days trying to get a server running and I haven't gotten any good help from the mineos forum. UPDATE: someone on another forum figured it out so nvm.
