Does anyone have an example of applying detekt inside a precompiled convention plugin for Gradle? When I try to follow https://docs.gradle.org/current/samples/sample_convention_plugins.html#compiling_convention_plugins, I'm getting

Unable to load class 'org.jetbrains.kotlin.gradle.dsl.KotlinJvmProjectExtension'.

This is an unexpected error. Please file a bug containing the idea.log file.

Strange, I'm doing basically the same thing (modulo the refreshVersions stuff), but I get

Do you have a classpath dependency on KGP?

[Sebastian Schuberth]

What's KGP?

[eygraber]

Kotlin Gradle Plugin

[eygraber]

You can add it to the classpath with org.jetbrains.kotlin:kotlin-gradle-plugin:<version>

[Sebastian Schuberth]

Hmm, could be. It might be hidden inside a subprojects clause, if that applied to buildSrc, too.

[eygraber]

It should be added either in settings.gradle.kts or in a buildscript.dependencies in your root build.gradle.kts

[Sebastian Schuberth]

Ah, so you're saying I should have a dependency on KGP? I though you were saying that having it might cause my problem.

[eygraber]

Right, you should have a dependency on KGP. Detekt's plugin is probably depending on it, but not propagating the transitive dependency to your project.
