Support bazelisk or bazel in tools/eclipse/project.py

It is recommended to use bazelisk instead of bazel directly, however
it is also perfectly reasonable to use bazel directly. Update the
eclipse script to default to looking for bazelisk then bazel, but to
continue to allow explicit overrides. This should allow people who
do not have bazelisk to not be broken, but people who have installed
bazelisk to have it be the program run by default.

This also causes whichever of the two was found to to go into
.bazel_path which will influence what eclipse uses.

Based on the change from Monty Taylor [1] in core Gerrit.

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_github_davido_bazlets",
  remote = "https://github.com/davido/bazlets.git",
  commit = "2ede19cb2d2dd9d04bcb70ffc896439a27e5d50d",
)
load("@com_github_davido_bazlets//:gerrit_api.bzl",
     "gerrit_api")

Another option is to consume snapshot version of gerrit plugin API from local Maven repository (~/.m2). To use the snapshot version special method is provided:

load("@com_googlesource_gerrit_bazlets//:gerrit_api_maven_local.bzl",
     "gerrit_api_maven_local")
gerrit_api_maven_local()

Basic Example

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

[workspace]/
    WORKSPACE
	BUILD
    src/main/java/
	src/main/resources/
	[...]

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"]),
    gwt_module = "com.googlesource.gerrit.plugins.reviewers.ReviewersForm",
    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.

gerrit_plugin

gerrit_plugin(name, srcs, resources, gwt_module, deps, manifest_entries):

Implicit output target

  • <name>.jar: library containing built plugin jar
