My modname_at.cfg works fine in the development environment, and it works when I run my mod in Eclipse, but when I build my mod and load it in the actual Minecraft client, it crashes due to a field  not being public:

 

java.lang.IllegalAccessError: tried to access field net.minecraft.world.WorldServer.field_73068_P from class lotr.common.LOTRTickHandlerServer

 

(This field is one of those made public in my modname_at.cfg, WorldServer.allPlayersSleeping)

 

Since this always seemed to work fine in 1.6, could anyone tell me if the method of doing this has changed somehow in 1.7, or what I am doing wrong and how I can fix it? Thank you.

 

This is my full access transformer file:

 

public net.minecraft.entity.player.EntityPlayer * 
public net.minecraft.entity.player.EntityPlayer *()
public net.minecraft.entity.player.EntityPlayerMP * 
public net.minecraft.entity.player.EntityPlayerMP *()
public net.minecraft.client.entity.EntityClientPlayerMP * 
public net.minecraft.client.entity.EntityClientPlayerMP *()
public net.minecraft.client.entity.EntityOtherPlayerMP * 
public net.minecraft.client.entity.EntityOtherPlayerMP *()

public net.minecraft.block.BlockCrops *()
public net.minecraft.block.BlockCarrot *()
public net.minecraft.block.BlockPotato *()

public net.minecraft.world.WorldServer *

public net.minecraft.client.renderer.entity.RenderPlayer *

public net.minecraft.potion.Potion *

public net.minecraft.entity.passive.EntityHorse *

public net.minecraft.inventory.InventoryCrafting *

public net.minecraft.block.BlockStem *

So I have to use IFMLLoadingPlugin? Okay then, I was not aware that those things had to be used for changing the visibility of fields and methods, because it worked fine before without them. And I made everything public because I haven't been able to find the srg names yet in the new gradle system.

 

Edit: Reflection is not an option for me, because the mod has to access things every tick, so there would probably be too much performance penalty.
