  1. C:\Users\TatTvaum\Desktop\Minecraft>java -jar forge-1.12.2-14.23.1.2562-universal.jar 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(Unknown Source) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.base/java.lang.reflect.Method.invoke(Unknown Source) at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.run(ServerLaunchWrapper.java:62) at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.main(ServerLaunchWrapper.java:31) Caused by: java.lang.ClassCastException: java.base/jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to java.base/java.net.URLClassLoader at net.minecraft.launchwrapper.Launch.<init>(Launch.java:34) at net.minecraft.launchwrapper.Launch.main(Launch.java:28) ... 6 more
  2. As in open CMD, pasta, press enter? Doesn't do anything. If you mean as in opening minecraft_server.1.12.2.jar and pasting it, then it gives me "Unknown command. Try /help for a list of commands" error. There are really no other command lines.
  3. As in creating a .bat file with the text "-jar forge-1.12.2-14.23.1.2562-universal.jar" and running it? Doesn't do anything, except instantly open and reclose CMD.
  4. As you can tell from the picture, I have the latest recommended revision of Forge. I've now tried to reinstall it twice, and it still doesn't work. The minecraft_server.1.12.2.jar file executes and runs everything without any errors, but the highlighted forge-1.12.2-14.23.1.2562-universal.jar file will do nothing whatsoever when I try to open it. No window appearing, no nothing. Any ideas as to what can be causing this? I've updated Java and Java SE Development kit etc. So this can't be causing the issue either. Thanks in advance.
