Build scripts that publish pre-compiled protoc artifacts
protoc is the compiler for .proto files. It generates language bindings
for the messages and/or RPC services from .proto files.
Because protoc is a native executable, the scripts under this directory
build and publish a protoc executable (a.k.a. artifact) to Maven
repositories. The artifact can be used by build automation tools so that users
would not need to compile and install protoc for their systems.
Versioning
The version of the protoc artifact must be the same as the version of the
Protobuf project.
Artifact name
The name of a published protoc artifact is in the following format:
protoc-<version>-<os>-<arch>.exe, e.g., protoc-3.0.0-alpha-3-windows-x86_64.exe.
System requirement
Install Apache Maven if you don't have it.
The scripts only work under Unix-like environments, e.g., Linux, MacOSX, and
Cygwin or MinGW for Windows. Please see README.md of the Protobuf project
for how to set up the build environment.
To install artifacts locally
The following command will install the protoc artifact to your local Maven repository.
$ mvn install
Cross-compilation
The Maven script will try to detect the OS and the architecture from Java system properties. It's possible to build a protoc binary for an architecture that is different from what Java has detected, as long as you have the proper compilers installed. For example, MingGW32 only ships with 32-bit compilers, but you can still build 32-bit protoc under a 64-bit system, with the following command:
$ mvn install -Dos.detected.arch=x86_32
To push artifacts to Maven Central
Before you can upload artifacts to Maven Central repository, make sure you have read this page on how to configure GPG and Sonatype account.
Use the following command to upload artifacts:
$ mvn clean deploy -P release
