Q:

Switch from --go_out=plugins to -go-grpc_out PATH problem

I'm trying to setup an older go/grpc project of mine, about 4 months since last change, and protoc and protoc-gen-go seems to have changed a lot. 
back in the days I was able to generate the files with something like:
protoc --go_out=plugins=grpc:. * .proto

As it is still documented at:
https://github.com/golang/protobuf
But trying to run this todays gives the following error:
--go_out: protoc-gen-go: plugins are not supported; use 'protoc --go-grpc_out=...' to generate gRPC

Ok, so I tried to use the --go-grpc_out flag, but:
Please specify a program using absolute path or make sure the program is available in your PATH system variable

What am I missing?  protoc-gen-go is registered in the path, as you can see when using the old command. 
Thanks in advance

A:

Answer: protoc-gen-go-grpc: program not found or is not executable
Short v1.2 of protoc-gen-go doesn't support plugins anymore.  And will be replaced by protoc-gen-go-grpc, which I coulnd't find. 
BUT! 
github.com/golang/protobuf version of protoc-gen-go-grpc still and will be supporting plugins.
