I have been developing my mod over the past few weeks for forge build 1180 for 1.7.10. In eclipse everything works perfectly but when I build the mod and load it with forge (build 1180) it crashes!

 

This is the crash report:

At line 20 and 50 it says that it is caused by java.lang.NoClassDefFoundError: items/ItemEnergizedShardSpeed and java.lang.ClassNotFoundException: items.ItemEnergizedShardSpeed. Im not sure what this means but the classe ItemEnergizedShardSpeed is in the items package. Im not sure what the issue is.

Thanks in advance

Hi

 

Have you called the package directory Items instead of items by any chance?

 

-TGG

No, I dont think thats the case. Everything referring to the package is spelled with a lower case. In the crash report it points towards line 394 in my main class, RunicScrolls.java. This is the item registry for the shard.

itemEnergizedShardSpeed = new ItemEnergizedShardSpeed().setUnlocalizedName("itemEnergizedShardSpeed").setCreativeTab(scrollTab).setTextureName(modid + ":" + "itemEnergizedShardSpeed");
	GameRegistry.registerItem(itemEnergizedShardSpeed, "itemEnergizedShardSpeed");

This is the full main class: http://pastebin.com/xmMnyzd1

 

This is also everything inside the class for ItemEnergizedShardSpeed;

package items;

 

import java.util.List;

 

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.item.Item;

import net.minecraft.item.ItemStack;

public class ItemEnergizedShardSpeed extends Item 
{
public void addInformation(ItemStack par1ItemStack, EntityPlayer par2EntityPlayer, List par3List, boolean par4) 
{
    	par3List.add("Made in an Endite Reactor");
    }
}

 

This is a download for this crashing version of my mod : http://www.fileswap.com/dl/X3nVhTLQA5/modid-1.0.jar.html

 

I cant see anything wrong with it.

 

Ok, I fixed it. A lot of stuff was missing form the build folder and was named incorrectly. I fixed it by changing the names and directories.
