Posted October 26, 20222 yr I built a 1.16.5 server for my kid. He's been having a blast with it for a few months. But now he wants to try an MC version 1.18.2 server using forge version 40.1.60. I did what I've done before and something is wrong. I run the forge server without any mods and it starts up fine. I add any mod and it crashes with errors like the below. Where am I messing up here? I've been trying to fix this for two days. Any help would be much appreciated. 1.18.2 - 40.1.60 - forge version 1.18.2 minecraft version C:\Users\dave9\Documents\Minecraft Server 1.18.2>java @user_jvm_args.txt @libraries/net/minecraftforge/forge/1.18.2-40.1.60/win_args.txt 2022-10-26 06:17:06,865 main WARN Advanced terminal features are not available in this environment [06:17:07] [main/INFO] [cp.mo.mo.Launcher/MODLAUNCHER]: ModLauncher running: args [--launchTarget, forgeserver, --fml.forgeVersion, 40.1.60, --fml.mcVersion, 1.18.2, --fml.forgeGroup, net.minecraftforge, --fml.mcpVersion, 20220404.173914] [06:17:07] [main/INFO] [cp.mo.mo.Launcher/MODLAUNCHER]: ModLauncher 9.1.3+9.1.3+main.9b69c82a starting: java version 19.0.1 by Oracle Corporation [06:17:07] [main/INFO] [mixin/]: SpongePowered MIXIN Subsystem Version=0.8.5 Source=union:/C:/Users/dave9/Documents/Minecraft%20Server%201.18.2/libraries/org/spongepowered/mixin/0.8.5/mixin-0.8.5.jar%2314!/ Service=ModLauncher Env=SERVER [06:17:07] [main/WARN] [ne.mi.fm.lo.mo.ModFileParser/LOADING]: Mod file C:\Users\dave9\Documents\Minecraft Server 1.18.2\libraries\net\minecraftforge\fmlcore\1.18.2-40.1.60\fmlcore-1.18.2-40.1.60.jar is missing mods.toml file [06:17:07] [main/WARN] [ne.mi.fm.lo.mo.ModFileParser/LOADING]: Mod file C:\Users\dave9\Documents\Minecraft Server 1.18.2\libraries\net\minecraftforge\javafmllanguage\1.18.2-40.1.60\javafmllanguage-1.18.2-40.1.60.jar is missing mods.toml file [06:17:07] [main/WARN] [ne.mi.fm.lo.mo.ModFileParser/LOADING]: Mod file C:\Users\dave9\Documents\Minecraft Server 1.18.2\libraries\net\minecraftforge\lowcodelanguage\1.18.2-40.1.60\lowcodelanguage-1.18.2-40.1.60.jar is missing mods.toml file [06:17:07] [main/WARN] [ne.mi.fm.lo.mo.ModFileParser/LOADING]: Mod file C:\Users\dave9\Documents\Minecraft Server 1.18.2\libraries\net\minecraftforge\mclanguage\1.18.2-40.1.60\mclanguage-1.18.2-40.1.60.jar is missing mods.toml file [06:17:07] [main/INFO] [ne.mi.fm.lo.mo.JarInJarDependencyLocator/]: No dependencies to load found.

October 26, 20222 yr Use java 17, mixin does not support java 19 Boilerplate: If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one. If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install Large files should be posted to a file sharing site like https://gist.github.com You should also read the support forum sticky post.
October 26, 20222 yr Author I'll be damned that fixed it. I uninstalled java 19, installed 17, and it's working. Thanks!
