# In the pullJarFiles function in tools/binary-repo-lib.sh it executes find commands
# to search for .desired.sha1 files, which contain sha1 hashes that are appended
# to ${BURI} along with the subdirectory and filename to form the list of jar files

# find . -name \*.desired.sha1 -exec sed -e 's@\([0-9a-f]*\).*@\1@' {} \; -print
# After editing it into the desired format: sort -t / -k 3 file
