Forge code missing?

mod_MinecraftForge has a bunch of errors in it, and when i attempted to repair the imports they werent the same as  what it wanted.

It says it cant find NetworkMod.java, and the major and minor versions variables in ForgeHooks.

It also couldnt find getDungeonLootTries in MinecraftForge, or init in MinecraftForgeClient, OR killMinecraft in minecraftforge.

code:

package net.minecraft.src;

import net.minecraftforge.client.*;
import net.minecraftforge.common.*;


/**
* This class is just here to make the Forge version show up nicely in the ModLoader logs/Crash Screen
*/
public class mod_MinecraftForge extends NetworkMod
{
    @MLProp(info = "Set to false to reproduce a vinella bug that prevents mobs from spawning on inverted half-slabs and inverted stairs.")
    public static boolean SPAWNER_ALLOW_ON_INVERTED = true;
    
    @Override
    public String getVersion()
    {
        return String.format("%d.%d.%d.%d",
                ForgeHooks.majorVersion,    ForgeHooks.minorVersion,
                ForgeHooks.revisionVersion, ForgeHooks.buildVersion);
    }

    @Override
    public void load()
    {
        MinecraftForge.getDungeonLootTries(); //Random thing to make things Initialize
        MinecraftForgeClient.init();
    }
}
