Well, I'm having trouble running an example of already compiled code in real minecraft package (no package eclipse), when I run in eclipse, runs without any problem, but when I move the compiled code into the mods folder in the directory the real minecraft (.minecraft) I get the message NoSuchMethodError. I'll post the example code and the error message.

 

Class Generic (init class)

package tutorial.generic;

import tutorial.generic.items.GenericItem;
import tutorial.generic.items.GenericMetaItem;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.item.Item;
import cpw.mods.fml.common.Mod;

@Mod(modid = "generic", name = "Generic", version = "0.0.0")
public class Generic {

@Instance(value = "generic")
public static Generic instance;

@SidedProxy(clientSide = "tutorial.generic.client.ClientProxy", serverSide = "tutorial.generic.CommonProxy")
public static CommonProxy proxy;

public static Item genericItem,genericMetaItem;

@EventHandler
public void preInit(FMLPreInitializationEvent event) {
	genericItem = new GenericItem().setMaxStackSize(64).setCreativeTab(CreativeTabs.tabMisc).setUnlocalizedName("genericItem").setTextureName("generic:nickelCrystal");

	GameRegistry.registerItem(genericItem, "GenericItem");
}

@EventHandler
public void init(FMLInitializationEvent event) {
}

@EventHandler
public void postInit(FMLPostInitializationEvent event) {
}

}

 

Class GenericItem

package tutorial.generic.items;

import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.item.Item;

public class GenericItem extends Item {

public GenericItem() {
                super();
}
}

 

Class CommonProxy

package tutorial.generic;

public class CommonProxy {

// Client stuff
public void registerRenderers() {
	// Nothing here as the server doesn't render graphics or entities!
}
}

 

Class ClientProxy

package tutorial.generic.client;

import tutorial.generic.CommonProxy;
import net.minecraftforge.client.MinecraftForgeClient;

public class ClientProxy extends CommonProxy {

@Override
public void registerRenderers() {
	// This is for rendering entities and so forth later on
}
}

forge version:

Minecraft forge-1.7.10-10.13.2.1230

 

Note. When I change the code setMaxStackSize(64) by maxStackSize = 64 in constructor,  the exception changes to NoSuchFieldError.

 

Well this is my problem, can someone help me?

I only found tutorials on how to use gradlew for installation, how can I use to build my mod? can you give me a hint? and thanks for the reply = b

He answered that question already, actually. You need to use the command

 

gradlew build

 

This post has all the information you will ever need (for basic stuff) on ForgeGradle:

 

http://www.minecraftforge.net/forum/index.php?topic=14048.0#post_compiling

compiled by gradlew and it worked, but now I have another problem, when I run the game the item customized it not renders (instead renders a box of pink and black), the directory where the texture is located assets / generic / textures / items / NickelCrystal.png.

I call on item setTextureName ("generic: nickelCrystal");

This works fine when I do the eclipse, when I put the game simply does not render correctly. is there anything else I should do?

 

Note: i check for the textures files in jar and its ok

 

grateful again for the answers.

The pink and black box is the "texture missing" texture. Check the logs, they should be spammed with something like:

 

[Client thread/ERROR]: Using missing texture, unable to load <blah>.png
java.io.FileNotFoundException: <blah>

 

This will tell you where your mod is looking for the textures, versus where they are actually placed.

your upper and lower case must match in jars.

 

eg NickelCrystal.png is not the same as nickelCrystal.png

here :

[02:53:57] [Client thread/ERROR]: Using missing texture, unable to load generic:textures/items/nickelCrystal.png

 

hehe, my bad i did write "nickelCrystal" in setTextureName(), when its use uppercase ("NickelCrystal.png"), now its every ok ty for all =b
