# Helper script for updating androidx.test prebuilts from maven
#
# Usage:
#   a. Initialize android environment eg . build/envsetup.sh; lunch <target>
#   b. Update the version numbers in this file
#   c. ./prebuilts/misc/androidx-test/update-from-gmaven.py
#
# The script will then:
#   1. Remove the previous artifacts
#   2. Download the aars and poms into a file structure mirroring their maven
#      path
#   3. Extract the AndroidManifest from the aars into the manifests folder
#   4. Run pom2bp to generate the Android.bp
