# Pre-create the Gradle build directories this tree will write into.
#
# WHY: this worker may run under FreeBSD's Linuxulator (podman on FreeBSD, no
# Linux kernel). There, Java NIO's Files.createDirectories - which Gradle uses
# to create build/reports/... - fails with
#   "Failed to create parent directory '<mod>/build' when creating directory
#    '<mod>/build/reports/<tool>'"
# even though a plain `mkdir -p` of the same path succeeds. The workaround is
# to create the parent directories before Gradle runs; Gradle then finds them
# existing and does not need the failing path. On a real Linux kernel this
# script is a harmless no-op.
#
# Usage: prepare-build-dirs.sh [root]
#   root defaults to the current directory.
