build.gradle: unable to resolve class com.google.common.collect.ImmutableMap

[Hans-Christoph Steiner <hans@at.or.at>]

I'm trying to update the Android gradle plugin (java/groovy/gradle) to
the latest release in time for stretch.  I already updated the dependent
lib android-platform-frameworks-data-binding to 2.2.2 and uploaded that.
 Seamlik uploaded
android-platform-tools-analytics-library and this is already using that.
 Now I'm stumped by a build.gradle that is importing a Java class from
libguava, but its not being found.  This advanced gradle is a bit beyond
me.  My work is all current in their respective git repos.

android-platform-tools-base:

import com.google.common.collect.ImmutableMap

apply plugin: 'java'
apply plugin: 'jacoco'

Here's the stacktrace:
