Another Maven Protocol Buffers Plugin

Another Maven Protocol Buffers Plugin uses Protocol Buffer Compiler (protoc) tool to generate Java source files from .proto (protocol buffer definition) files for the specified project. For more information about the Protocol Buffer Compiler, please refer to Reference Guide.

The Plugin automatically scans all project dependencies for bundled .proto files, and configures proto_path of the Protocol Buffer Compiler to use those files as imports.

The Plugin automatically attaches the source .proto files to the resources of the project, so that they are later packaged into the final artifact and can be referenced as imports from the dependent projects or modules.

Goals Overview

Another Maven Protocol Buffers Plugin has the following goals:

protobuf:compile compiles main .proto definitions into Java files and attaches the generated Java sources to the project.
protobuf:test-compile compiles test .proto definitions into Java files and attaches the generated Java test sources to the project.
protobuf:compile-cpp compiles main .proto definitions into C++ files and attaches the generated C++ sources to the project.
protobuf:test-compile-cpp compiles test .proto definitions into C++ files and attaches the generated C++ test sources to the project.
protobuf:compile-python compiles main .proto definitions into Python files and attaches the generated Python sources to the project.
protobuf:test-compile-python compiles test .proto definitions into Python files and attaches the generated Python test sources to the project.
protobuf:compile-csharp compiles main .proto definitions into C# files and attaches the generated C# sources to the project.
protobuf:test-compile-csharp compiles test .proto definitions into C# files and attaches the generated C# test sources to the project.
protobuf:compile-js compiles main .proto definitions into JavaScript files and attaches the generated JavaScript sources to the project.
protobuf:test-compile-js compiles test .proto definitions into JavaScript files and attaches the generated JavaScript test sources to the project.
protobuf:compile-descriptor-set generates a descriptor set from main .proto definitions.
protobuf:test-compile-descriptor-set generates a descriptor set from test .proto definitions.
protobuf:compile-custom compiles main .proto definitions using a custom protoc plugin.
protobuf:test-compile-custom compiles test .proto definitions using a custom protoc plugin.
