Need Sample for grpc with Maven about lagom-samples HOT 4 CLOSED

Related to akka/akka-grpc#1103

from lagom-samples.

Hi @venkateshzifo, I've put together a couple of commits in https://github.com/ignasi35/lagom-samples/commits/lagom-grpc-maven. You can test the application using:

cd grpc-example/grpc-example-java
sbt test

or with the new maven build:

cd grpc-example/grpc-example-java
mvn clean verify -e

I've added you as co-author on the commit and I'll push that code as a PR.

hi @venkateshzifo, this sounds like a OS-level PROXY setup is affecting your dev mode.

See this discussion (lagom/lagom#1575) for more details on how to solve th issue.
