I'm mainly asking this for the modpack "Material Energy Classic" by parcel31u, but how would I convert a modpack into a server pack with the mods. I've tried looking at the differences between the "SevTech: Ages" modpack and it's server pack counterpart and tried to mimic what was different by isolating the overrides folder and renaming it "serverpack" as the SevTech serverpack only includes what's in the overrides folder. I've also added the forge universal file for the minecraft version of MEC, 1.6.4, but when i try to start the forge universal, it just brings up this error: We appear to be missing one or more essential library files. You will need to add them to your server before FML and Forge will run successfully.java.lang.ClassNotFoundException: net.minecraft.launchwrapper.Launch 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) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at cpw.mods.fml.relauncher.ServerLaunchWrapper.run(ServerLaunchWrapper.java:30) at cpw.mods.fml.relauncher.ServerLaunchWrapper.main(ServerLaunchWrapper.java:17) How do I convert a mod pack into a server pack so I can play it with friends?
