The protocol buffers code: https://github.com/protocolbuffers/protobuf
Reference: https://developers.google.com/protocol-buffers/

This repository contains Java Protocol Buffers Nano compiler plugin and runtime library. Google published the Java Nano code for a short time, then stoped supporting it, and removed the code. The repository contains that code, made compile again. It consists of the two following components.

Should be build with Maven. To generate .jar file, cd into "javanano" and run:

 $ mvn package

To Install it into your Maven repository:

 $ mvn install

See the javanano README for more details.

Allows compiling the the .proto file into Java nano. To build, run:

 $ bazel build ...

You would need to install Bazel, see https://bazel.build for more details.

The resulting binary will be:

bazel-bin/protoc-gen-javanano

Place it into a directory included in your PATH, and run:

protoc --javanano_out=<dir> <NormalProtoParams>

Note, this compiles against a specific protoc version: not sure if it'll work well with a different protoc. See the WORKSPACE file for that version.
