flogo binary not getting generated for grpc recipes

Create an app using 'flogo create -f flogo.json'
~/go/src/github.com/project-flogo/grpc/examples/json/rest-to-grpc/MyProxy$ flogo build

Skip the grpc code generation step and manually add the following to the imports.go file:

_ "github.com/project-flogo/grpc/proto/rest2grpc"

your imports.go file should look like this:

package main

import (
_ "github.com/project-flogo/contrib/trigger/rest"
_ "github.com/project-flogo/microgateway"
_ "github.com/project-flogo/grpc/activity"
_ "github.com/project-flogo/grpc/proto/rest2grpc"
)

Should now be working. Use latest cli and GRPC. GRPC docs have been updated.

_ "github.com/project-flogo/grpc/proto/rest2grpc"
)

Based on the quoted import statement, it seems the app will listen rest request to trigger flow. How can grpc client call the flow?
