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

These 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.

$ ./gradlew install

To push artifacts to Maven Central

Before you can upload artifacts to Maven Central repository, you must have set up your account with OSSRH, and have generated a PGP key for siging. You need to put your account information and PGP key information in $HOME/.gradle/gradle.properties, e.g.:

signing.keyId=24875D73
signing.password=secret
signing.secretKeyRingFile=/Users/me/.gnupg/secring.gpg

ossrhUsername=your-jira-id
ossrhPassword=your-jira-password

Use the following command to upload artifacts:

$ ./gradlew uploadArchives
