# Expect maven log as the first argument.
# There are two requirements for the maven log:
# 1. It needs to be produced by a recent maven version (such as 3.5.4 installed by
# bin/bootstrap_system.sh). This is required because recent maven outputs line like:
# [INFO] Downloading from {repo}: {url}
# [INFO] Downloaded from {repo}: {url}
# Older maven (e.g. 3.3.9) omits the "from {repo}" part.
# 2. Maven needs to run in batch mode (-B). This keeps the output from using special
# characters to format things on the console (e.g. carriage return ^M).
