Protocol Buffers protobuf maven plugin - performs protobuf code generation using protoc-jar multi-platform executable protoc JAR. Available on Maven Central: https://repo.maven.apache.org/maven2/com/github/os72/protoc-jar-maven-plugin/3.11.4/
Simple maven plugin to compile .proto files using protoc-jar embedded protoc compiler, providing some portability across the major platforms (Linux, Mac/OSX, and Windows). At build time the plugin detects the platform and executes the corresponding protoc binary.
Supports embedded protoc versions 2.4.1, 2.5.0, 2.6.1, 3.11.4, and any binaries (protoc and protoc plugins) available for download from maven central. Also supports pre-installed protoc binary
