How to use go mod tidy with go_deps when working with .proto files?

[Megakuul]

Hello, I have a question about how to use the go_deps gazelle extension in a project where I use proto files.

So I have a bzlmod project where I use go with grpc proto files. As I read here it is recommended to manage external dependencies with the go.mod file and use the gazelle go_deps extension. I did this and everything works like expected, however if I try to update the dependencies with bazel run @rules_go//go -- mod tidy -v it does not find the imported proto file:

go: github.com/megakuul/cthulhu/shared/dbadapter/go imports
        github.com/megakuul/cthulhu/shared/dbadapter/rpc/etcdv3: no matching versions for query "latest"

Now, I'm confused how this problem can be solved because I would rather not precompile the proto files into my source tree (which would then make it work). I assume I could also add a replace directive in the go.mod file that points the proto imports to the bazel-out files, but this seems like a terrible idea to me.

Does anyone see what I'm doing wrong here or have an idea how to work with that correctly?

I found a discussion in rules_go that suggests to use:

bazel run @io_bazel_rules_go//go -- mod tidy -e

To ignore errors and continue trying to update the go.mod file.

Thanks, even if that doesn't seem to be a very clean solution, it works.

In the meantime, I have changed my project to include the protobuf output in the repository; I think this is generally the more appropriate approach for many projects, as it allows external programs outside the monorepo to depend on the precompiled api definitions.
