As I mentioned, I am getting java.lang.NullPointerException every time I try to access my own item group or reaching the end All Items or when I give Infused Soul Shard using /give command.

Other items and blocks work fine. Infused Soul Shard is somehow causing game crashes. It works fine when I comment rows 55-169 in items.InfusedSoulShard.

I think that problem is in tooltips, but I'm not really sure. Could anybody help me please? Here's link to my project with log enclosed.

Because your item group is created the minute your first item gets constructed, which is before the fields in your ModItem class have been given values via the @ObjectHolder annotation.

 

This is why ModItemGroup exists:

How can I implement HardLib to gradle? I tried to add an existing github project to my build.gradle file but all my attempts have failed? I didn't find any HardLib 1.14.4 jar files. Is there any other way make ItemGroup construct after items are given values?

Don't. I forgot that that was my class. Just create it yourself in your own project:

I am not getting item group errors now, but game still crashes if rows 54-168 in Infused Soul Shard are not commented. I think getItemStackLimit method is extra because my maximum stack size is 1 if soul shard is unbound, but it isn't a reason of crash. Could you check it please?

Man, if only I knew what line the crash was on and what the error was.

I found out where the problem was. The problem was that I didn't have config variable in main group. I changed MODID to public and added an annotation above class EventHandler. Do I need EasyRegistry items to see them in all items in creative? If I add group(ItemGroup.jassa) to item properties, I can see all items and blocks two times in group jassa.
