I have recently begun playing with my friends on my own minecraft server. I felt like I had done enough and wanted to play on the server modded. I started by downloading forge's modded server and started setting up. When i tried to launch the modded program it gave me the error Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=256M; support was removed in 8.0 A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.run(ServerLaunchWrapper.java:70) at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.main(ServerLaunchWrapper.java:34) Caused by: java.lang.NoClassDefFoundError: org/apache/logging/log4j/Level at net.minecraft.launchwrapper.Launch.launch(Launch.java:94) at net.minecraft.launchwrapper.Launch.main(Launch.java:28) ... 6 more Caused by: java.lang.ClassNotFoundException: org.apache.logging.log4j.Level at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 8 more I didn't understand what this meant. I looked up the error and found out that other people were having the same error. I reinstalled the server and all the dependent programs and I still can't manage to fix it. I am using 1.12.2 server and need help. If anyone can help let me know.
