Kotlin and Android Development featuring Jetpack: apply plugin vs plugins {...} (page 37)

Jeff,
You’re correct that the second version is the current way to write out plugins, but the old version should still work.
Also, a heads up that the version you posted has a few issues. You’re missing colons after plugin and the first plugin is missing a dot after android:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'

Let me know if that works!
