So I wanted to compile Gunpowder-Utilities because the version on curseforge doesn't seem to work for 1.18.2, but I got this error:

Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.

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/7.4.2/userguide/command_line_interface.html#sec:command_line_warnings

I was confused, so I tested with the template, same error. I tested with 0.3.7 instead of 0.3.6, same error.

It seems you have the incorrect link to your maven in the Project.kt file. You have https://maven.martmists.com/ when it should be https://maven.martmists.com/releases
