How to print used proto specification version (pdata and otlp protobuf version different)

[suiluj]

Hello, I am developing a custom file exporter and want to compare the currently used proto specification versions.

So my thought process is to write the version while exporting and reading it back and comparing it with the currently running version of an exporter.

At the moment I am reading versions of used packages like this:

bi, ok := debug.ReadBuildInfo()
if !ok {
	return nil, errors.New("failed to read build info")
}

for _, dep := range bi.Deps {

	log.Default().Println(dep.Path, dep.Version)

}

This way I can get information like this:

go.opentelemetry.io/collector v0.71.0
go.opentelemetry.io/collector/pdata v1.0.0-rc5

But I would like the get the information that the collector uses v0.19.0 at the moment

something like:

open-telemetry/opentelemetry-proto-go  v0.19.0
# or
opentelemetry-proto  v0.19.0

I need this information because I am planning to interact with the proto definitions and custom grpc servers too. And the versions should be forwarded to have automatic compatibility checks when processing files.

Does someone have an idea on how to extract this v0.19.0 information from a running collector?
