Gerrit Code Review Rules for Bazel

Overview

These build rules are used for building Gerrit Code Review plugins with Bazel. Plugins are compiled as .jar files containing plugin code and dependencies.

Setup

To be able to use the Gerrit rules, you must provide bindings for the plugin API jars. The easiest way to do so is to add the following to your WORKSPACE file, which will give you default versions for Gerrit plugin API.

git_repository(
  name = "com_googlesource_gerrit_bazlets",
  remote = "https://gerrit.googlesource.com/bazlets",
  commit = "928c928345646ae958b946e9bbdb462f58dd1384",
)
load("@com_googlesource_gerrit_bazlets//:gerrit_api.bzl", "gerrit_api")
gerrit_api()

The version parameter allows to override the default API. For release version numbers, make sure to also provide artifacts' SHA1 sums via the plugin_api_sha1 and acceptance_framework_sha1 parameters:

load("@com_googlesource_gerrit_bazlets//:gerrit_api.bzl", "gerrit_api")
gerrit_api(version = "3.2.1",
           plugin_api_sha1 = "47019cf43ef7e6e8d2d5c0aeba0407d23c93699c",
           acceptance_framework_sha1 = "6252cab6d1f76202e57858fcffb428424e90b128")

If the version ends in -SNAPSHOT, the jars are consumed from the local Maven repository (~/.m2) per default assumed to be and the SHA1 sums can be omitted:

load("@com_googlesource_gerrit_bazlets//:gerrit_api.bzl", "gerrit_api")
gerrit_api(version = "3.3.0-SNAPSHOT")

Basic Example

Suppose you have the following directory structure for a simple plugin:

[workspace]/
├── src
│   └── main
│       ├── java
│       └── resources
├── BUILD
└── WORKSPACE

To build this plugin, your BUILD can look like this:

load("//tools/bzl:plugin.bzl", "gerrit_plugin")

gerrit_plugin(
    name = "reviewers",
    srcs = glob(["src/main/java/**/*.java"]),
    manifest_entries = [
        "Gerrit-PluginName: reviewers",
        "Gerrit-Module: com.googlesource.gerrit.plugins.reviewers.Module",
    ],
    resources = glob(["src/main/**/*"]),
)

Now, you can build the Gerrit plugin by running bazel build <plugin>.

For a real world example, see the reviewers plugin.
