Edit: Solved

After updating to Kotlin 1.9.20 I get the following error:

Plugin [id: 'org.jetbrains.kotlin.kapt'] was not found in any of the following sources:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (plugin dependency must include a version number for this source)

It was working fine before like this:

plugins {
  kotlin("kapt")
}

It seems to work if I manually add the version:

plugins {
  kotlin("kapt") version "1.9.20"
}

Looks like the issue was KGP classloader issues. Adding a classpath dependency on KGP solved the issue

Indeed Kapt plugin is a part of KGP jar. Though following should work:

plugins {
    id("org.jetbrains.kotlin.kapt") version "2.0.0-Beta1"
}
