You simply have to use

isPublish = true

or

setPublish(true)

Thanks, @jnizet.

Our Kotlin example in the docs is wrong. We're missing a few tests in PackagingDocumentationTests as well.

@wilkinsona Note that the wrong publish property is used in the plugin documentation. I'm working on a PR to fix it.
