Hi, How do I get arguments in TaskProvider#configure lambda? If you look at Google’s code, it is receiving arguments from configure, but when I actually try it, an error appears. Also, I checked if Google has overridden the TaskProvider#configure function, but I couldn’t find it.

Have you tried to remove the argument (jarTask) and directly use this?
(I presume it's not the same method/version between both projects)

Hi Grégory Lureau, thanks for the reply.
Did you mean this?

The task is the context receiver to the lambda and not an argument. So you would want something like jarTask = this as Jar .

Or use tasks.named<Jar>("jar") { // this is now a Jar

wow mkrussel you are awesome. Thanks everyone!

You might want to consider enabling the Lambda Kotlin inlay hints . It can clear up a lot of these types of confusion.

Thanks for the great tip till the end!

Kotlin has a sam-with-receiver compiler plugin.
With this plugin you can specify classes / interfaces for which you can use foo.configure { doSomething() } instead of foo.configure { it.doSomething() }. In the Kotlin DSL (and also if you apply the kotlin-dsl plugin to a project) this plugin is configured to for example include the Action interface. In the Google code you linked, this compiler plugin is not active, so you have to use the foo.configure { it.doSomething() } version there.
