Are there any sample libraries publishing with the new plugin dsl and an Android aar? I have jvm and native publishing with gradle 4.7, and am able to publish with the older "platform" plugin, but not clear on how it would work with the newer dsl.

It's not supported yet. See https://youtrack.jetbrains.com/issue/KT-27535

Yeah. Ugh. That sucks. Doing major plumbing work on the db library. Got everything working with the new plugin except the publish.

Yeah it's a little unfortunate. Hopefully soon though.
