[on_and_off]

I have a project with Kotlin + Dagger + DataBinding.

Annotation processing works fine with kotlin.

First setup can be a pain though, especially if you are not familiar with Android or the gradle build system.

I'm hopeful that with official support this process will become smoother

It was rough because I had to write the script myself (one year ago). You need to know some things that are not obvious at first glance, like the fact that the databinding compiler is versioned with the android plugin for gradle.

Nowadays, you can just copy paste it from an existing github project.
