tools/pkg_war.bzl: Use .to_list() on web_xml.files

While compiling gitiles, I see this error (edited to fit in commit msg)

$ bazel build //:gitiles
ERROR: gitiles/BUILD:3:1: in _pkg_war rule //:gitiles:
Traceback (most recent call last):
File "gitiles/BUILD", line 3 While compiling

	for web_xml in ctx.attr.web_xml.files: ...
type 'depset' is not iterable. Use the `to_list()` method to get a list.
Use --incompatible_depset_is_not_iterable=false to temporarily disable this check.

Using to_list() as recommended seems to solve the problem.

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"]),
    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, deps, manifest_entries):

Implicit output target

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