In a quixotic attempt to avoid duplication I've put this in

settings.gradle.kts

, but now I'm worrying that Gradle won't know that a change to

gradle/libs.versions.toml

invalidates the plugins section of

settings.gradle.kts

. Is this a terrible idea?

plugins {
  id("com.autonomousapps.build-health") version "2.13.0"

  val kotlinVersion = rootDir.resolve("gradle/libs.versions.toml")
    .readLines()
    .dropWhile { !it.matches("""^\h*\[\h*versions\h*\]\h*$""".toRegex()) }
    .drop(1)
    .takeWhile { !it.matches("""^\h*\[""".toRegex()) }
    .firstNotNullOf {
      """^\h*kotlin\h*=\h*"(?<version>[^"]*)"\h*$""".toRegex()
        .matchEntire(it)?.groups?.get("version")?.value
    }

  // Kotlin must be loaded in the same (or parent) class loader as the
  // Dependency Analysis Plugin. The lines below are one way to accomplish this
  id("org.jetbrains.kotlin.jvm") version kotlinVersion apply false
}

You could use a includedBuild instead 🤔

I'm fairly sure that won't work with the

com.autonomousapps.build-health

because it won't load the kotlin classes in the correct classloader, which is the reason why I'm loading the

org.jetbrains.kotlin.jvm

plugin in the

settings.gradle.kts

plugins

block.

Well, I can add build-health next days but it should work. Or just fork it and test it.

But won't that then be applying the

com.autonomousapps.build-health

plugin in individual subprojects

build

rather than as a settings plugin? I'm pretty hazy as to the difference between settings plugins and build plugins but I think they're different, and the

com.autonomousapps.build-health

plugin documentation says it should be applied as a settings plugin: https://github.com/autonomousapps/dependency-analysis-gradle-plugin/wiki/Adding-to-your-project#via-the-build-health-settings-plugin

You can write convention settings plugins too :)

OK, I'll look into that. Thanks.

This is what I did with the MyRepos settings plugin, that loads the included build classpath into the root settings classpath including the KGP and build-Health dependency
