Task with name 'clean' not found in root project

Filing and closing so that this becomes searchable for others in the future (hopefully helpful if you're inheriting a project that you didn't originally setup)

I originally filed #858 (comment) a while back. The gist was that setting up spotless didn't work out of the box with an android project. There was a "workaround" needed, and now after updating spotless to the latest version the workaround isn't needed anymore so you can return the old code that used to be there.

Workaround:

tasks.named("clean", Delete::class) { delete(rootProject.buildDir) }

Fix: (basically revert to what a standard android app comes with out of the box)

tasks.register("clean", Delete::class) {
    delete(rootProject.buildDir)
}
