Maybe this is due to a new version of Java and I should download a previous one, for example: Java 8 Update 391?

Hi, I wanted to switch from Aternos cloud server to my own. 1. I downloaded the latest version: forge-1.12.2-14.23.5.2859.jar for the server. 2. Made start.bat java -Xmx10G -Xms10G -jar forge-1.12.2-14.23.5.2859.jar nogui pause 3. An error occurred in the log file: [09:40:23] [main/INFO] [LaunchWrapper]: Loading tweak class name net.minecraftforge.fml.common.launcher.FMLServerTweaker [09:40:23] [main/INFO] [LaunchWrapper]: Using primary tweak class name net.minecraftforge.fml.common.launcher.FMLServerTweaker [09:40:23] [main/INFO] [LaunchWrapper]: Calling tweak class net.minecraftforge.fml.common.launcher.FMLServerTweaker And this appeared in the console: 2024-02-03 09:48:07,632 main ERROR Error processing element Queue ([Appenders: null]): CLASS_NOT_FOUND 2024-02-03 09:48:07,676 main WARN Disabling terminal, you're running in an unsupported environment. 2024-02-03 09:48:07,715 main ERROR Unable to locate appender "ServerGuiConsole" for logger config "root" [09:48:07] [main/INFO] [LaunchWrapper]: Loading tweak class name net.minecraftforge.fml.common.launcher.FMLServerTweaker [09:48:07] [main/INFO] [LaunchWrapper]: Using primary tweak class name net.minecraftforge.fml.common.launcher.FMLServerTweaker [09:48:07] [main/INFO] [LaunchWrapper]: Calling tweak class net.minecraftforge.fml.common.launcher.FMLServerTweaker 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: com/google/common/collect/Lists at net.minecraftforge.fml.common.launcher.FMLTweaker.acceptOptions(FMLTweaker.java:69) at net.minecraftforge.fml.common.launcher.FMLServerTweaker.acceptOptions(FMLServerTweaker.java:36) at net.minecraft.launchwrapper.Launch.launch(Launch.java:114) at net.minecraft.launchwrapper.Launch.main(Launch.java:28) ... 6 more Caused by: java.lang.ClassNotFoundException: com.google.common.collect.Lists 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) ... 10 more If you need to know, I have already updated Java to Version 8 Update 401. I also tried the same thing on another computer and had the same problem.
