Configuration with Minecraft - ATM 9 modpack

Technical Support

OS Name/Version: Ubuntu 22.04 LTS

Product Name/Version: AMP 2.5.1.2 - 20240724.5

Problem Description:
We have an existing server with ATM9-To The Sky modpack and its associated server files. We are unable to locate which jar file the modpack is using as its server jar, because the start scripts do not reference a server jar.

Script contents:
the associated line is:

 "${ATM9_JAVA:-java}" @user_jvm_args.txt @libraries/net/minecraftforge/forge/1.20.1-$FORGE_VERSION/unix_args.txt nogui

jvm args contains the memory max variable, so we can ignore that. The other one, however is the one we’re confused at because no where in that other args file references the actual Forge-version-server.jar or Forge-version-universal.jar
See below for the unix_args.txt file it is referencing.

Actions taken to resolve so far:
Examined scripts and files to find the jar so we can add the jar to the root of the instance folder and have AMP take it.

We’re not sure how to configure the settings in AMP to get the below to run properly with the forge server jar we found.

You just need to tell AMP its a forge based server and which forge version. It’ll take care of the rest.

Yep. I’m used to the old way of doing it where you just had the forge server jar in the root… It works. sorry for the topic. thanks for the help!
