To specify the path for the “google/protobuf/any.proto” file when generating code in Golang, you can use the “import_path” flag with the protoc command.
For example, let’s say your “any.proto” file is located in the following directory:
/home/user/go/src/github.com/google/protobuf/src/google/protobuf/
To generate code using this file, you would run the following command:
protoc --go_out=plugins=grpc:. --proto_path=/home/user/go/src/github.com/google/protobuf/src/ import_path=github.com/google/protobuf/src/google/protobuf any.proto
Note that you need to provide the full import path of the file, starting from the root of your project. Also, make sure that the path you provide for the “proto_path” flag includes the directory containing the “google/protobuf” package.
