I recently started programming mods with automated data generation and i tried to create a custom stair and a custom slab block.

The generated json files(in src/generated/resources/assets) are correct, however when i start the client these files are not found:

If I place the generated json in the manually-generated folder(src/main/resources/assets) everything works, so I do not think that there are some errors in the json files. What strikes me is that other blocks, like example_block and example_block2, that are auto-generated and placed in src/generated/resources/assets work perfectly.

I need to do something special for blocks like stairs/slabs/fences to make their json files seen by minecraft? What am I doing wrong?

Here it is:

buildscript {

        // These repositories are only for Gradle plugins, put any other repositories in the repository block further below

}

I removed the duplicate files and tried running the game with the data auto generated, and it works. I didn't change anything and I cannot understand because now works and 2 hours before it didn't. Maybe it is related to some cache issues? Maybe there is a cache that needs to be cleaned?

Anyway, thanks for the help mate!
