Cannot resolve symbol 'ItemGroup'

[ConsumerOfCocaCola]

I am trying to add a new item, but It says that It cant resolve symbol ItemGroup. For some reason it doesn't let me import item group because it cant resolve "Item" or something. I am using the latest MDK with IntelliJ Idea. I am having an error with Item.Properties().group and the one after that. 

 

public static final RegistryObject<Item> SODA = ITEMS.register("soda", () -> new Item(new Item.Properties().group(ItemGroup.MATERIALS)));

You seem to be using a tutorial for pre-1.16 which uses the old MCP names. 1.17+ fully uses mojmaps for classes, methods, and fields. I would recommend joining the discord to get access to Forge bot to transform the names between mappings. Alternatively, you could use linkie, which is more general instead of for Forge.

To answer your question, `Item$Properties#group` is now `#tab` and `ItemGroup#MATERIALS` is `CreativeModeTab#TAB_MISC`.
