Dependencies of `com_github_grpc_grpc` are not loaded

shs96c commented 1 year ago

Issue Description

After loading //:repositories.bzl and calling rules_proto_grpc_repos, dependencies required by com_github_grpc_grpc are not loaded, notably build_bazel_rules_apple, which is used by grpc_build_system.bzl.

All the deps would be loaded properly if @com_github_grpc_grpc//bazel:grpc_dep.bzl was loaded and grpc_deps() called.

Log Output

$ bazel build //proto:amazing_python_grpc

Yes you need to add those dependencies as documented in the per-lang docs: https://rules-proto-grpc.com/en/latest/lang/python.html#python-grpc-library. These have to be done by you at top level WORKSPACE, since we cannot both declare a dependency and load from it within rules_proto_grpc_repos or similar.

@aaliddell I'm sorry, but where are these extra dependencies documented? There don't seem to be any mention of additional dependency requirements on the link you shared. Is it the extra_deps()? Searching for the exact missing dependency yields 0 results: https://rules-proto-grpc.com/en/4.5.0/search.html?q=build_bazel_rules_apple&check_keywords=yes&area=default#

In the workspace section of the 4.5.0 docs there's a load and call to the extra deps: https://rules-proto-grpc.com/en/4.5.0/lang/python.html#id21

load("@rules_proto_grpc//python:repositories.bzl", rules_proto_grpc_python_repos = "python_repos")

rules_proto_grpc_python_repos()

load("@com_github_grpc_grpc//bazel:grpc_deps.bzl", "grpc_deps")

grpc_deps()

load("@com_github_grpc_grpc//bazel:grpc_extra_deps.bzl", "grpc_extra_deps")

grpc_extra_deps()
