Goodafternoon, im just an idiot who is trying to learn how to mod minecraft, i was following this tutorial https://www.youtube.com/watch?v=55qUIf3GMss&t=197s  when at min 12 it says to execute in the console ./gradlew genIntelliJruns (i have no idea what this does) and it got me an error: 

> Task :createSrgToMcp FAILED

FAILURE: Build failed with an exception.

* What went wrong:

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

See https://docs.gradle.org/8.1.1/userguide/command_line_interface.html#sec:command_line_warnings

BUILD FAILED in 21s

I have no idea how to solve it nor if it is important to do so. 
Can someone help me?
Thank you.

Does the text at line 35 of the gradle.properties folder read "mapping_channel=official"? if it does, change the "official" part to "parchment". Hope this helps.
