how to upgrade to 0.41.0 via bzlmod only

[pdeva]

the upgrade instruction for 0.41.0 mention this as step 1:

http_archive(
    name = "googleapis",
    sha256 = "9d1a930e767c93c825398b8f8692eca3fe353b9aaadedfbcf1fca2282c85df88",
    strip_prefix = "googleapis-64926d52febbf298cb82a8f472ade4a3969ba922",
    urls = [
        "https://github.com/googleapis/googleapis/archive/64926d52febbf298cb82a8f472ade4a3969ba922.zip",
    ],
)

load("@googleapis//:repository_rules.bzl", "switched_rules_by_language")

switched_rules_by_language(
    name = "com_google_googleapis_imports",
)

this seems to be for users of WORKSPACE file.

What is the equivalent to the above for those looking to use bzlmod only?

Try this:

MODULE.bazel

GOOGLE_APIS_VERSION = "64926d52febbf298cb82a8f472ade4a3969ba922"

bazel_dep(name = "com_google_googleapis", version = GOOGLE_APIS_VERSION)
archive_override(
    module_name = "com_google_googleapis",
    integrity = "sha256-nRqTDnZ8k8glOYuPhpLso/41O5qq3t+88fyiKCyF34g=",
    patch_strip = 1,
    patches = [
        "add_bzlmod_support.patch"
    ],
    strip_prefix = "googleapis-" + GOOGLE_APIS_VERSION,
    urls = [
        "https://github.com/googleapis/googleapis/archive/%s.zip" % GOOGLE_APIS_VERSION
    ],
)

switched_rules = use_extension("@com_google_googleapis//:extensions.bzl", "switched_rules")
switched_rules.use_languages()
use_repo(switched_rules, "com_google_googleapis_imports")

add_bzlmod_support.patch

Note to anybody trying this at home: if you see an error like this:

no such package '@[unknown repo 'googleapis' requested from @gazelle~0.34.0~go_deps~com_github_grpc_ecosystem_grpc_gateway]//google/api'

then you need to patch Gazelle to pull in googleapis so that its extension modules can see it.

In your MODULE.bazel, change Gazelle from a bazel_dep to a git_override (note that single_version_override won't work). Then add a patch like this:

diff --git MODULE.bazel MODULE.bazel
index e272b19..41f4c71 100644
--- MODULE.bazel
+++ MODULE.bazel
@@ -5,6 +5,7 @@ module(

+bazel_dep(name = "googleapis")
 bazel_dep(name = "protobuf", version = "3.19.6", repo_name = "com_google_protobuf")
 bazel_dep(name = "rules_go", version = "0.42.0", repo_name = "io_bazel_rules_go")
 bazel_dep(name = "rules_proto", version = "4.0.0")

Now all the Go deps that Gazelle pulls in will be able to find googleapis!

Trying this with latest versions but i get this:
