I have been following the tutorial by Kaupenjoe on YouTube and I cant seem to get the .json files to generate and all my blocks and items to work or show textures.

I’m using minecraft 1.20.4 forge.

This is the video I am using – > https://www.youtube.com/watch?v=enzKJWq0vNI&list=PLKGarocXCE1H9Y21-pxjt5Pt8bW14twa-&index=13

Here is my git repo:

I have tried to run the gradel run button for data gen and it dosent work.
One possible problem is this statement, which is not a error but i feel like can be a problem , =>
Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

I am not sure how to fix it can anyone please help.
