Mod Broke Upon Updating Versions

Status
Works as designed
Issue description

Several items from my mod just randomly stopped working when I updated versions. Any reasons this could be? (I would attach file but it's too big)

Issue comments

Most of the food elements in my mod became errors, despite me not changing any code in them at all between versions. It's the randomest of the items, too. Raw Bacon works, but cooked bacon doesn't. Cheese becomes an error, bread slice becomes an error (and toast doesn't), etc etc etc. Half of these items don't have any special properties or anything.

Here's every error involved with the cheese food item alone:

Did you even read the page I linked?

If this page did not explain to you things, you should not be using the code locking system in the first place.

Use code lock feature only if you know at least some Java and Forge basics. Without this knowledge, changing code will likely result in build errors you will not be able to understand without this knowledge.

How else am I supposed to have giant items in my mod? If I don't lock the code it just makes it small again. And the items that don't work aren't locked items.

items that don't work aren't locked items.

Because they reference them in code. As I said:

I see you still did not read the page:

  1. Keep the files locked and manually apply needed changes
  2. Unlock the files so MCreator can update them for you, but this will overwrite all your changes in these files, so you need to lock them back after updating and re-apply the changes

I did unlock the files, but it still won't work. I tried deleting my gradle folder to see if that would work, but no matter what I tried, the folder wouldn't delete.

you could for example add a option to only lock resource files (json files)

This is planned :)

No, not yet, but i'm fairly sure the next version is planning to do just that

What do you mean?

I did. I unlocked every last thing.
