# A script to upload a given java_tools zip on GCS. Used by the java_tools_binaries
# Buildkite pipeline. It is not recommended to run this script manually.

# Script used by the "java_tools binaries" Buildkite pipeline to build the java tools archives
# and upload them on GCS.
#
# The script has to be executed directly without invoking bazel:
# $ src/upload_all_java_tools.sh
#
# The script cannot be invoked through a sh_binary using bazel because git
# cannot be used through a sh_binary.
