ERROR: java.lang.NoSuchFieldError: world

I`m writing a simple mod, that must find water block near player after command in chat.

Main mod class:

import net.minecraftforge.common.MinecraftForge;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.Mod.EventHandler;
import net.minecraftforge.fml.common.event.FMLInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPreInitializationEvent;
import org.apache.logging.log4j.Logger;

@Mod(modid = QMod.MODID, useMetadata=true, clientSideOnly = true)
public class QMod {
    public static final String MODID = "qmod";

    public static Logger logger;

    @EventHandler
    public void preInit(FMLPreInitializationEvent event) {
        logger = event.getModLog();
    }

    @EventHandler
    public void init(FMLInitializationEvent event) {
        logger.info("Init");
        MinecraftForge.EVENT_BUS.register(new ChatListener(logger));
    }
}

ChatListner:

import net.minecraft.client.Minecraft;
import net.minecraftforge.client.event.ClientChatEvent;
import net.minecraftforge.fml.client.FMLClientHandler;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
import org.apache.logging.log4j.Logger;


public class ChatListener {
    static Logger logger;

    ChatListener(Logger lg) {
        logger = lg;
    }

    @SubscribeEvent
    public void ClientChatEvent(ClientChatEvent e) {
        logger.info("MESSAGE");
        logger.info(e);
        Minecraft mc = FMLClientHandler.instance().getClient();
        logger.info(mc);
        logger.info(mc.world);
        if (e.getMessage().contains(".find")) {
            logger.info("EEEE");
            e.setCanceled(true);
            BottleFiller bottleFiller = new BottleFiller(logger, mc);
            bottleFiller.scanBlocks();
        }
    }
}

If I lauch client with "gradle lauchClient" everything is OK. But when I try to launch it from the launcher(placed builded .jar into mods folder) an error occurs:

Also instead of FMLClientHandler.instance().getClient() I used Minecraft.getMinecraft() but this didn't help.

What am I doing wrong?
