# @DESCRIPTION:
# A directory relative to ${S} which contains the source code.
# source code distributed by Maven Central are exactly the root of
# the source code, we need to assign them a separate directory to
# avoid the situation that the source code, the resources and the
# source code for testing are mixed in ${S}.

# @DESCRIPTION:
# A directory relative to ${S} which contains the resources of the
