snippetsDir and the kotlin dsl

I created a new project with Gradle + Kotlin + Boot 2.1.5 and these dependencies:

• Spring Boot Dev Tools
• Rest Repositories
• Spring Rest Docs
• Spring Boot Actuator

The Initializer create this build.gradle.kts file (shorten):

extra["snippetsDir"] = file("build/generated-snippets")

tasks.test {
	outputs.dir(snippetsDir)
}

tasks.asciidoctor {
	inputs.dir(snippetsDir)
	dependsOn(test)
}

But imo it should be:

val snippetsDir by extra { file("build/generated-snippets") }

tasks.test {
    outputs.dir(snippetsDir)
}

tasks.asciidoctor {
    inputs.dir(snippetsDir)
    dependsOn(tasks.test) // added tasks. prefix
}

I also prefer @tristanlins proposal which seems more idiomatic Gradle Kotlin DSL code.

Thanks for the report.

In addition to the proposed solution, an alternative would be to leave the declaration of the snippetsDir property as it is and to change how it is referenced:

tasks.test {
	outputs.dir(project.property("snippetsDir"))
}

tasks.asciidoctor {
	inputs.dir(project.property("snippetsDir"))
	dependsOn(tasks.test)
}

The alternative is more closely aligned with what we currently do for bom imports, but I think I prefer the proposal from @tristanlins. If we go with that approach, we should review how we define and reference properties for bom imports as well.
