Instructions

This project generates from the istio/api the Java classes using the Google Protobuf protoc converter. The tool can be installed locally using this brew command brew install protobuf.

If Golang is already installed on you machine, then download the Google Protobuf project as it is used to convert different Google types such as ExtensionRegistry, ExtensionRegistryLite, MessageOrBuilder, ...

go get github.com/google/protobuf

Next, clone the istio api project which contains the definition of the mixer, broker and proxy types

cd /path/to/go/workspace/src/istio.io
git clone https://github.com/istio/api

Create locally a new project to host the Java classes generated

mkdir -p java_model/src/main/java
