# We run multiple processes in parallel by passing the -j option to Make.
# If multiple recipes call Gradle, it is likely that those recipes will be executed in parallel.
# Gradle jobs do not like being run in parallel; it causes all kinds of nonsense errors.
# To solve this, we use flock. Flock checks if a file is locked. If it is, it waits until it isn't.
# Once it isn't locked, it locks it, runs the command, then unlocks it once the command is finished.
# Note that flock doesn't ship on macOS. You can install it with `brew install flock`
# On Windows, flock comes with Cygwin.
