# 1. Compare the third-party dependencies with known dependencies, expect that all third-party dependencies are KNOWN
# and the exit code of the command is 0, otherwise we should add its license to LICENSE file
# [dolphinscheduler-dist/release-docs/LICENSE] and [dolphinscheduler-dist/release-docs/licenses/]
# and add the dependency to known-dependencies.txt.
#
# 2. Unify the `sort` behaviour: here we'll sort them again in case that the behaviour of `sort` command in
# target OS is different from what we used to sort the file `known-dependencies.txt`, i.e. "sort the two file
# using the same command (and default arguments)"
