Check all binary proto plugin installed in $GOPATH/bin

setting up google annotation proto

cd ~ && \
git clone https://github.com/googleapis/googleapis/tree/master/google/api && \
sudo cp -a ~/googleapis/google/api /usr/local/include/google/api

Configure IDE import path to include google annotation proto

When the import path completed Then IDE will not give error in line import "google/api/annotations.proto";

build pb, run code generator
