# This is a workaround to Issue 316936462: after the initial build with $BAZEL_OPTS
# that include a remote cache, the subsequent implicit build commands executed would
# expect the cache to be remote and fail to download the artifact if the $BAZEL_OPTS
# are not passed. Because the 'bazel build' commands are dynamically generated, the
# only way to pass the extra parameters is via .bazelrc
