我想在1.16.3中编写一个minecraft mod。我已经在1.12.2中做了一个mod，但是我没有这个问题。我只是下载了1.16.3 forge mdk并为eclipse构建了它（cmd中带有“gradlew eclipse”），但是当我尝试运行mod时（带有“runclient.launch”）。它给出了一个错误：
noclassdeffounderror:jdk/nashorn/api/scripting/nashornscriptenginefactory。
我试图修改主文件和包，以支持不需要的代码，但当我开始。它给了我同样的错误。
我的主文件：

package fr.luzog78.newmod;

import net.minecraft.block.Blocks;
import net.minecraftforge.common.MinecraftForge;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.event.lifecycle.FMLClientSetupEvent;
import net.minecraftforge.fml.event.lifecycle.FMLCommonSetupEvent;
import net.minecraftforge.fml.javafmlmod.FMLJavaModLoadingContext;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

@Mod("newmod")
public class NewMod {
    private static final Logger LOGGER = LogManager.getLogger();

    public NewMod() {
        FMLJavaModLoadingContext.get().getModEventBus().addListener(this::setup);
        FMLJavaModLoadingContext.get().getModEventBus().addListener(this::doClientStuff);

        MinecraftForge.EVENT_BUS.register(this);
    }

    private void setup(final FMLCommonSetupEvent event) {
        LOGGER.info("HELLO FROM PREINIT");
        LOGGER.info("DIRT BLOCK >> {}", Blocks.DIRT.getRegistryName());
    }

    private void doClientStuff(final FMLClientSetupEvent event) {
    }

//    @SubscribeEvent
//    public void onServerStarting(FMLServerStartingEvent event) {
//        // do something when the server starts
//        LOGGER.info("HELLO from server starting");
//    }
//
//    // You can use EventBusSubscriber to automatically subscribe events on the contained class (this is subscribing to the MOD
//    // Event bus for receiving Registry Events)
//    @Mod.EventBusSubscriber(bus=Mod.EventBusSubscriber.Bus.MOD)
//    public static class RegistryEvents {
//        @SubscribeEvent
//        public static void onBlocksRegistry(final RegistryEvent.Register<Block> blockRegistryEvent) {
//            // register a new block here
//            LOGGER.info("HELLO from Register Block");
//        }
//    }
}

以及堆栈跟踪：
