I am trying to learn Go modules dependency manager but getting an error while importing auto-generated proto definitions. Have been struggling with this for 2 days. Any help will be greatly appreciated. Directory structure:
➜ ~/go-service-skeleton> tree .
.
├── protobuf
│ └── test_service
│ ├── test_service_config.pb.go
│ └── test_service_config.proto
├── src
│ └── test_service
│ ├── go.mod
│ ├── main.go
│ └── server
│ └── server.go
Error (last error is particularly concerning):
➜ ~/go-service-skeleton/src/test_service go build

Within your test_service module, the only dependencies visible to the go command are the ones declared in its go.mod file.
The simplest fix is to put all of the source code you need inside the main module. Note that per https://blog.golang.org/generate, “if the containing package is intended for import by go get, once the file is generated (and tested!) it must be checked into the source code repository to be available to clients.”
