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

Caused by: java.lang.NoClassDefFoundError: org/jetbrains/kotlin/gradle/dsl/KotlinJvmProjectExtension

Do you have a classpath dependency on KGP?

What's KGP?

Kotlin Gradle Plugin

Hmm, could be. It might be hidden inside a

subprojects

clause, if that applied to

buildSrc

, too.

It should be added either in

settings.gradle.kts

or in a

buildscript.dependencies

in your root

build.gradle.kts

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

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.
