Doesn't that contain the log?

I wasn't sure which log you wanted

[I'm new to modding, can someone help me fix this 1.17 issue i found in mcjty's mod tutorial?]

It says that the import will not resolve

 

[I'm new to modding, can someone help me fix this 1.17 issue i found in mcjty's mod tutorial?]

And when i remove the world from the import, an error line show up that was not there before.

Here are the logs

Where would I find my log?

[I'm new to modding, can someone help me fix this 1.17 issue i found in mcjty's mod tutorial?]

package com.Charlie.items;

import net.minecraft.world.item.Item;

public class TestItem extends Item{

	public TestItem(Properties properties) {
		super(properties);
		// TODO Auto-generated constructor stub
	}

}

There is the TestItem class, and i even made sure to import it into the Registration file, which is why I am so confused. There is an error line beneath the part where I imported the class that says that that import is unused. 

[I'm new to modding, can someone help me fix this 1.17 issue i found in mcjty's mod tutorial?]

It did not work. I think that the errors are in line 23, this one right here

public static final RegistryObject<Item> TESTITEM = ITEMS.register("testitem", () -> new TestItem(new Item.Properties()));

it has an error line underneath register that says "The method register(String, Supplier<? extends I>) in the type DeferredRegister<Item> is not applicable for the arguments (String, Supplier<capture#2-of ? extends I>)"

And the Error line underneath TestItem says that "TestItem cannot be resolved to a type"

Thanks, I will try that right now.

package com.Charlie.items;

import com.Charlie.items.TestItem;

	private static final DeferredRegister<Item> ITEMS = DeferredRegister.create(ForgeRegistries.ITEMS, MODID);
	
	public static void init() {

	}
	
	public static final RegistryObject<Item> TESTITEM = ITEMS.register("testitem", () -> new TestItem(new Item.Properties()))
	
}

Thats the registry code, do you need any of the other code?

I was trying to make a very simple item with no properties, and the minecraft client will not start, and it says that the mod failed to load.

[I'm new to modding, can someone help me fix this 1.17 issue i found in mcjty's mod tutorial?]

I tried to follow along to his tutorial, but when I got to the end and tried to test it out for myself, it would not load properly. It keeps the same error messages, and none of Eclipse's quickfixes help or seem to affect anything whatsoever. I don't know what to do and would appreciate any help. The error message it gives is:

The method register(String, Supplier<? extends I>) in the type DeferredRegister<Item> is not applicable for the arguments (String, Supplier<capture#2-of ? extends I>)
