# This script is designed to run on a buildbot to build from the source

# r8-release Cloud Storage Bucket.
#
# These files are uploaded:
#
# raw/desugar_jdk_libs/<VERSION>/desugar_jdk_libs.jar
# raw/desugar_jdk_libs/<VERSION>/desugar_jdk_libs.zip
# raw/com/android/tools/desugar_jdk_libs/<VERSION>/desugar_jdk_libs-<VERSION>.jar
#
# The first two are the raw jar file and the maven compatible zip file. The
# third is the raw jar file placed and named so that the URL
# https://storage.googleapis.com/r8-releases/raw can be treated as a maven
# repository to fetch the artifact com.android.tools:desugar_jdk_libs:1.0.0
