This is ultramine core fork aimed to work with GT:NH

Currently you need to do 2 things:

1. Delete archaicfix mod from you mods folder
2. Delete coretweaks or edit config file config/coretweaks.cfg and disable diagnostics.detect_data_watcher_id_conflicts:

   diagnostics {
     detect_data_watcher_id_conflicts {
         # Emit warning when a mod registers a typed DataWatcher object in an already occupied ID slot (vanilla only warns in the typeless registration method). [default: true]
         S:_enabled=false
   
         # Keep track of all registration stack traces, and print which ones conflict. Off by default because it adds some overhead to DataWatcher object registration. [default: false]
         B:detectDataWatcherIdConflictCulprit=false
     }
     enhance_map_storage_errors {
         # Makes MapStorage's errors more informative. [default: true]
         S:_enabled=true
     }
   }

Seems like ultramine can be run on modern java without any modifications (at least on my private server it runs fine).

Here is how to do it:

1. You need to get lwjgl3fy-forgePatches compatible with ultramine
   • Here is prebuild version of lwjgl3fy 2.1.4: https://github.com/SKProCH/ultramine_core/releases/download/v0.4/lwjgl3ify-2.1.4-master+ea93d147db-dirty-forgePatches.jar
   • Or you can compile it by yourself from here
     You need to edit build.gradle.kts and change libraryList

         manifest {
         val libraryList = listOf(
     

     It should include all the libraries from the libraries folder, and "forge-1.7.10-10.13.4.1614-1.7.10-universal.jar", "minecraft_server.1.7.10.jar" should be replaced to ultramine jar name, like "ultramine_core-server.jar".
     Here is the example for current repo.
     After that use forgePatchesJar target.
2. Rename ultramine server core jar to "ultramine_core-server.jar" (or whatever name you included to libraryList if you are compiled lwjgl3fy by yourself)
3. Rename forgePatches files to lwjgl3ify-forgePatches.jar
4. Create a file named java9args.txt with the contents of
   • This file if you are using prebuild lwjgl3fy 2.1.4 from my releases
   • Or this file if you compile it by yourself from sources
5. You can now launch the server with a command like the following, assuming the first java executable on your PATH is java 11/17/21/22:

    java -Xmx6G -Xms6G @java9args.txt -jar lwjgl3ify-forgePatches.jar nogui
