net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from ScudMissileMod (scud)

Caused by: java.lang.NoClassDefFoundError: net/minecraft/client/Minecraft at scud.message.Handler_MAZ543Full.<init>(Handler_MAZ543Full.java:14)

Your problem is the ScudMissileMod trying to load client classes on the server.

The mod author no longer supports that mod: https://www.curseforge.com/minecraft/mc-mods/scud-missile-mod

and minecraft 1.12 is also no longer supported in these forums.
