does kotlin script support automatic SAM conversion ? I get an error when I do val action = Action<String> { println(it) }

Action<T> is treated specially in build scripts and in projects using the kotlin-dsl plugin

[bamboo]

Whereas a regular SAM interface with a fun execute(target: T): Unit would be treated as (T) -> Unit, Action<T> is treated as T.() -> Unit

Ok thanks, time for me to dig in the Kotlin documentation !

[mbonnin]

Just curious: what is that for ?

[bamboo]

This is so the it. qualifier is not needed when interacting with Action<T> based Gradle APIs, for instance, `Project.copy(Action<CopySpec>)`:

copy {
   from(“source”) // no `it.from`
   into(“target”)
}

[mbonnin]

I see

[bamboo]

Your snippet could be rewritten as:

val action: Action<String> = Action { println(this) }
action.execute("fooBar!")

[mbonnin]

Works fine, thanks 🙂

I was tryring to call plugins.all {}. Removing it works fine
