I've got an Error - but only in a "live environment"

Hello world.

Another error I don't understand, but  may be easy to solve if knowing how forge works.

 

When starting the mod on forge 2228 in IDE everything is fine, but if its loaded in the client I get

There was a severe problem during mod loading that has caused the game to fail

net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from Ancient Trees (dendrology)
Caused by: java.lang.NoSuchFieldError: CHESTS_VILLAGE_BLACKSMITH

 

CHESTS_VILLAGE_BLACKSMITH is a static field from the LootTableList, which definitely does exist.

 

Code where the error is thrown:

        final Map<ResourceLocation, Integer> map = Maps.newHashMap();
        map.put(CHESTS_VILLAGE_BLACKSMITH, 0);
        map.put(CHESTS_SPAWN_BONUS_CHEST, 0);
        map.put(CHESTS_DESERT_PYRAMID, 1);
        map.put(CHESTS_SIMPLE_DUNGEON, 1);
        map.put(CHESTS_JUNGLE_TEMPLE, 1);
        map.put(CHESTS_JUNGLE_TEMPLE_DISPENSER, 0);
        map.put(CHESTS_ABANDONED_MINESHAFT, 1);
        map.put(CHESTS_STRONGHOLD_CORRIDOR, 1);
        map.put(CHESTS_STRONGHOLD_CROSSING, 1);
        map.put(CHESTS_STRONGHOLD_LIBRARY, 1);
        map.put(CHESTS_END_CITY_TREASURE, 5);
        map.put(CHESTS_NETHER_BRIDGE, 5);
        map.put(CHESTS_IGLOO_CHEST, 1);
        return map;

 

It seems that none of these Fields exist in client. If I remove CHESTS_VILLAGE_BLACKSMITH, I get the same error on CHESTS_SPAWN_BONUS_CHEST ...

Oh, sorry. I used the wrong jars. Starting the mod with the obfuscated versions worked.
