Unable to load class during Gradle build

[Daeruin]

After a few months off, I'm trying to hurry and finish upgrading my mod to 1.18 before 1.20 comes out. I fired up IntelliJ and got this error:

Unable to load class 'org.gradle.api.internal.plugins.DefaultConvention'.

The only thing that's changed since last time I worked on my mod was updating to macOS Monterey. A little research seems to indicate the problem is with something trying to reference a class that's not available in the version of Gradle I'm using. My `gradle-wrapper.properties` is set to:

distributionUrl=https\://services.gradle.org/distributions/gradle-7.4-bin.zip

My project is set up to use the default Gradle wrapper and Java 17. I can see Gradle 7.4 in my /Users/<me>/.gradle folder. I also tried starting up a brand new mod project with the 1.18 Forge MDK and got the same error. Any idea what is going on here?

Show the entire error and the gradle buildscript.

I was able to reproduce the error using the gradle buildscript provided by the Forge MDK, version 1.18.2-40.1.0. I think this something wrong with my environment or IntelliJ settings. Here's the full error:

Sigh. I was being silly. I was using IntelliJ 2017. Once I opened my project in IntelliJ 2022, it worked fine.
