When I try to run the forge .jar file, I get this error in cmd prompt, and don't know what to do. 
 

The forge.jar is forge-1.12.2-14.23.5.2854-universal.jar, just renamed.


C:\Forge Server>java -Xmx16384M -Xms16384M -jar forge.jar nogui

1.12 is no longer supported on this forum. Please update to a modern version of Minecraft to receive support.

It's sad how much time mods spend saying "x is no longer supported on this forum. Please update to a modern version of Minecraft to receive support".

    • https://mclo.gs/46Xf7Sq thanks
    • That seems to have fixed it, thank you!
    • I am having some issues starting an RLCraft server on a minimal install of Debian 12. I have Java installed and I'm able to start the vanilla Minecraft server jar no problem and people can join and play without any issues, as soon as I try to create a new directory with the Forge jar the initial install with the INSTALLER jar works when I use the java command with the --installServer flag, but as soon as I try to start the server using the forge jar that is NOT labelled with installer I get the following error: A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException         at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)         at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:77)         at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)         at java.base/java.lang.reflect.Method.invoke(Method.java:569)         at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.run(ServerLaunchWrapper.java:70)         at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.main(ServerLaunchWrapper.java:34) Caused by: java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap')         at net.minecraft.launchwrapper.Launch.<init>(Launch.java:34)         at net.minecraft.launchwrapper.Launch.main(Launch.java:28)         ... 6 more   I have tried using newer versions of Java directly from Oracle as well. Has anybody been successful in starting and running a RLCraft server from the terminal on a Linux machine? I cannot figure out why it doesn't want to work but the vanilla jar works without issue. Thank you in advance!
    • This is my latest attempt :  public class ManaScreen extends Screen { Mana mana = new Mana(); boolean removeManaBar = false; ResourceLocation manaBar = ResourceLocation.fromNamespaceAndPath(RSGArmoury.MOD_ID, "/textures/block/spawnable_arena_wall.png"); public ManaScreen() { super(Component.literal("Mana")); } @Override protected void init() { super.init(); Minecraft.getInstance().setScreen(this); } @Override public boolean isPauseScreen() { return false; } @Override public void render(GuiGraphics pGuiGraphics, int pMouseX, int pMouseY, float pPartialTick) { pGuiGraphics.blit(manaBar, 10, -10, 0, 0, mana.getMana(), 10, mana.getMana(), 10); if (removeManaBar) { this.onClose(); return; } super.render(pGuiGraphics, pMouseX, pMouseY, pPartialTick); } public void addManaBar() { removeManaBar = false; Minecraft.getInstance().setScreen(new ManaScreen()); } public boolean removeManaBar() { return removeManaBar = true; } }
