missing com_google_cloud_sdk

[thehesiod]

I tried updating google/upvote to use 0.0.8 but then ran into:
/monolith_binary.deploy: line 26: ${{TMPDIR:-/tmp}}/war.XXXXXXXX: bad substitution
presumably due to double curly braces that seems to be fixed in the latest release.

Using head I get:
upvote/gae/BUILD:15:1: no such package '@com_google_cloud_sdk//': The repository could not be resolved and referenced by '//upvote/gae:monolith_binary.deploy'

ah, looks like I had to add:

load(
    "@io_bazel_rules_appengine//appengine:sdk.bzl",
    "appengine_repositories",
)

appengine_repositories()

may be worth mentioning in docs for post 0.0.8?

found another issue, on this line: https://github.com/bazelbuild/rules_appengine/blob/master/appengine/py/appengine_deploy.sh.template#L26

TMPDIR ends with a slash on my system, so you get a double slash, and a subsequent error because it can't find the directory. I fixed this on my system like so:

tmp_dir=$(echo ${TMPDIR:-/tmp}/war.XXXXXXXX | tr -s /)
tmp_dir="$(mktemp -d "${tmp_dir}")"

still have another error deploying, investigating

so now it seems like the requests_toolbelt.adapters is not getting loaded

update: I had to set overwrite_appengine_config = False, worth documenting as well for backwards compatibility
