/**
 * This script plugin is used to build and dist the test APK outputs of a library with multiple
 * build flavors.
 *
 * Compared to the defaults of the 'dist' plugin, it does two additional things:
 * 1. It builds the "debug" test APKs when the 'dist' task is run.
 * 2. It dist the test APKs using the original output file name instead of hard coding
 *    "${project.archivesBaseName}Tests.apk". This allows multiple flavors of test APKs to be built
 *    without conflicting file names.
