Is there a proper way to create a task for each source set, without using afterEvaluate? I want to make sure it is created even if the plugin that creates the source set is applied after mine...

in pseudcode

sourceSets.configureEach { s ->
  project.tasks.register("myCoolTask${s.name}") {
    ...
  }
}

ahh ok that makes sense. thanks!

(Until now) sourceSets are not lazy, so you are safe to call

all

too. And I don’t think they will be ever lazy

it's good practice to use configureEach universally. I used to think that Configurations would always be eager, but a recent Gradle release made them lazy. So now I have to go back and change all my `all`s to `configureEach`s. You never know and it doesn't hurt

As additional note: There is also

getTaskName

for a source set specific task name in the structure the core plugins name source-set-specific tasks. E.g.:

register(getTaskName("generate", "ExampleCode")) ...
