Protocol Buffers protobuf compiler - multi-platform executable protoc JAR and API. Available on Maven Central: https://repo.maven.apache.org/maven2/com/github/os72/protoc-jar/3.8.0/
Simple convenience JAR that embeds protoc compiler binaries for Linux, Mac/OSX, and Windows, providing some portability across the major platforms. At runtime the library detects the platform and executes the corresponding protoc binary. Supports embedded protoc versions 2.4.1, 2.5.0, 2.6.1, 3.8.0, and any protoc version available for download from maven central
