[Question] Migration from protoc-gen-validate to protovalidate

[rsylim804]

I am trying to use the migration tool provided under protovalidate to migrate from protoc-gen-validate but I am running into errors trying to download the git repository.

I am running go get github.com/bufbuild/[email protected] and getting this error in return:

go: github.com/bufbuild/[email protected] requires github.com/bufbuild/[email protected]: parsing go.mod:
	module declares its path as: github.com/envoyproxy/protoc-gen-validate
	        but was required as: github.com/bufbuild/protovalidate

Currently, we import protoc-gen-validate through bazel. Any ideas why I might be running into this and how to bypass this issue?

Hey, @rsylim804! There's no go module at the root of this project, so you'll need to go get github.com/bufbuild/protovalidate/tools@latest to get the module that contains the migrator.

(The error you're seeing is a red-herring related to caching in the go module proxy when we initially had this project live in the protoc-gen-validate repo itself.)

@rodaine Thanks for the reply! I'm running into a separate problem now trying to import protovalidate through bazel and getting it to build successfully.

Inside our BUILD file currently I have:
# gazelle:resolve proto proto buf/validate/validate.proto @protovalidate//proto/protovalidate/buf/validate:validate_proto
and
# gazelle:resolve proto go buf/validate/validate.proto @build_buf_gen_go_bufbuild_protovalidate_protocolbuffers_go//buf/validate:validate
However, I hit a cyclic dependency error trying to resolve the generated Go package for validate.proto with @org_golang_google_protobuf//cmd/protoc-gen-go:protoc-gen-go leading back to itself.

Is there a recommended way to get the migration to protovalidate working with Bazel?
