Migration Help from WORKSPACE to MODULE.bazel

[daniel-b2c2]

Description

I'm struggling to understand how to migrate from the old style workspace to the new MODULE.bazel. The world of grpc modules seems so fragmented it's hard to tell where the lines between different systems are, so my apologies if I'm asking in the wrong project.

Below is the WORKSPACE file, which I've split into parts with commentary, in order to migrate it to MODULE.bazel

All of this first bit can just be deleted from the WORKSPACE file

RULES_PROTO_GRPC_TAG = "4.6.0"

RULES_PROTO_GRPC_SHA = "2a0860a336ae836b54671cbbe0710eec17c64ef70c4c5a88ccfd47ea6e3739bd"

http_archive(
    name = "rules_proto_grpc",
    sha256 = RULES_PROTO_GRPC_SHA,
    strip_prefix = "rules_proto_grpc-%s" % RULES_PROTO_GRPC_TAG,
    urls = ["https://github.com/rules-proto-grpc/rules_proto_grpc/releases/download/%s/rules_proto_grpc-%s.tar.gz" % (RULES_PROTO_GRPC_TAG, RULES_PROTO_GRPC_TAG)],
)

Replaced the following section with bazel_dep(name = "rules_proto_grpc", version = "5.0.0") in the MODULE.bazel

load("@rules_proto_grpc//:repositories.bzl", "rules_proto_grpc_repos", "rules_proto_grpc_toolchains")

rules_proto_grpc_toolchains()

rules_proto_grpc_repos()

similarly below with bazel_dep(name = "rules_proto", version = "6.0.2")

load("@rules_proto//proto:repositories.bzl", "rules_proto_dependencies", "rules_proto_toolchains")

rules_proto_dependencies()

rules_proto_toolchains()

again below with bazel_dep(name = "rules_proto_grpc_java", version = "5.0.0")

load("@rules_proto_grpc//java:repositories.bzl", rules_proto_grpc_java_repos = "java_repos")

rules_proto_grpc_java_repos()

What is to be done with the following:

##
## Download and setup maven_grpc
##
load("@rules_jvm_external//:defs.bzl", "maven_install")
load("@io_grpc_grpc_java//:repositories.bzl", "IO_GRPC_GRPC_JAVA_ARTIFACTS", "IO_GRPC_GRPC_JAVA_OVERRIDE_TARGETS")

maven_install(
    name = "maven_grpc",
    artifacts = IO_GRPC_GRPC_JAVA_ARTIFACTS,
    generate_compat_repositories = True,
    override_targets = IO_GRPC_GRPC_JAVA_OVERRIDE_TARGETS,
    repositories = [
        "<URI_REDACTED>",
    ],
)

load("@maven_grpc//:compat.bzl", "compat_repositories")

compat_repositories()

load("@io_grpc_grpc_java//:repositories.bzl", "grpc_java_repositories")

grpc_java_repositories()

It may be enough to just load rules_proto_grpc_java in bazel_dep and bzlmod should handle all the transitive dependencies for you. You need to follow the migration guide in the docs also though: https://rules-proto-grpc.com/en/stable/changelog.html#id2

There are working examples in the /examples directory for each language also (ignore the local_path_override sections)
