Unable to install latest version of protoc-gen-validate using bazel

Bazel WORKSPACE configuration

Returned error

(16:03:44) ERROR: /private/var/tmp/_bazel_xxx/8853970899baaeb63ca98792c8fae39a/external/com_github_envoyproxy_protoc_gen_validate/BUILD:15:11: no such package '@com_github_lyft_protoc_gen_star//lang/go': The repository '@com_github_lyft_protoc_gen_star' could not be resolved and referenced by '@com_github_envoyproxy_protoc_gen_validate//:go_default_library'

Looks like bazel can not find the way to fetch @com_github_lyft_protoc_gen_star as protoc-gen-validate dependency or maybe it's required to be installed in another way with a different bazel configuration but I can not find any guideline for that. Could someone please help?

I am having similar issue.

Hit the same issue, and ended up adopting the bazel rules from rules-proto-grpc. It works pretty well.

[derekperkins]

@mindbergh could you clarify what you mean?

[mindbergh]

We tried to use protoc-gen-validate in our proto repo which uses bazel as the building tool. However, directly referencing this repo and using the rule located in https://github.com/envoyproxy/protoc-gen-validate/blob/main/bazel/pgv_proto_library.bzl gave us the same error as above. So we ended up using the rules provided by rules-proto-grpc and it builds the validator go files without error.

I faced the same error.

My workaround is loading dependencies of protoc-gen-validate explicitly like below:

git_repository(
    name = "protoc_gen_validate",
    commit = "8c0f6372216272771488d63323787e86377aefe0",
    remote = "https://github.com/envoyproxy/protoc-gen-validate",
)

load("@protoc_gen_validate//:dependencies.bzl", protoc_gen_validate_deps = "go_third_party")
protoc_gen_validate_deps()

It could be the wrong way, but generates expected pb.validate.go for me.

@110y I tested this, works on Linux (ubuntu), but not on macOS 😅

I have the same issue now. Gazelle generates the dependency as following in my project (deps.bzl):

    go_repository(
        name = "com_github_lyft_protoc_gen_star_v2",
        importpath = "github.com/lyft/protoc-gen-star/v2",
        sum = "h1:keaAo8hRuAT0O3DfJ/wM3rufbAjGeJ1lAtWZHDjKGB0=",
        version = "v2.0.1",
    )

But in protoc-gen-validate the name of the go_repository is com_github_lyft_protoc_gen_star without "v2". So this triggers the error when trying to build:

ERROR: /private/var/tmp/_bazel_alexandre.miziara/f7366cb40f218cae24698ffbd08f4bf3/external/com_envoyproxy_protoc_gen_validate/BUILD.bazel:18:11: no such package '@com_github_lyft_protoc_gen_star//': The repository '@com_github_lyft_protoc_gen_star' could not be resolved: Repository '@com_github_lyft_protoc_gen_star' is not defined and referenced by '@com_envoyproxy_protoc_gen_validate//:protoc-gen-validate_lib'
