Gazelle没有创建正确的依赖关系吗？

Question

考虑一个存储库github.com/myacct/sandbox，其顶部有一个ji目录：

$ ls -CFR
.:
BUILD.bazel  WORKSPACE  one/

./one:
oneonone.go

$ cat BUILD.bazel
load("@bazel_gazelle//:def.bzl", "gazelle")

# gazelle:prefix github.com/myacct/sandbox/ji

gazelle(name = "gazelle")

很标准的东西，直接从文档里拿出来。我已经运行了bazel clean --expunge。现在：

$ bazel run //:gazelle
Starting local Bazel server and connecting to it...
INFO: Analyzed target //:gazelle (66 packages loaded, 7036 targets configured).
INFO: Found 1 target...
Target //:gazelle up-to-date:
  bazel-bin/gazelle-runner.bash
  bazel-bin/gazelle
INFO: Elapsed time: 23.191s, Critical Path: 5.81s
INFO: 49 processes: 13 internal, 36 linux-sandbox.
INFO: Build completed successfully, 49 total actions
INFO: Build completed successfully, 49 total actions

让我们看看它做了什么：

$ cat one/BUILD.bazel
load("@io_bazel_rules_go//go:def.bzl", "go_binary", "go_library")

go_library(
    name = "one_lib",
    srcs = ["one.go"],
    importpath = "github.com/symbiont-io/sandbox/ji/one",
    visibility = ["//visibility:private"],
    deps = [
        "@org_golang_google_api//calendar/v3:go_default_library",
        "@org_golang_google_api//people/v1:go_default_library",
        "@org_golang_x_net//context:go_default_library",
        "@org_golang_x_oauth2//:go_default_library",
        "@org_golang_x_oauth2//google:go_default_library",
    ],
)

go_binary(
    name = "one",
    embed = [":one_lib"],
    visibility = ["//visibility:public"],
)

deps看起来不错，这就是我在one.go中导入的内容。

下面是它失败的原因：

$ bazel build //one:one
ERROR: /home/ji/sandbox/ji/one/BUILD.bazel:3:11: no such package '@org_golang_google_api//people/v1': The repository '@org_golang_google_api' could not be resolved and referenced by '//oneonone:oneonone_lib'
ERROR: Analysis of target '//one:one' failed; build aborted: Analysis failed

我发现文档实际上是非常详尽的。

无论如何，您需要运行update-repos。您可以运行一次性命令来导入所需的特定存储库：

bazel run //:gazelle -- update-repos google.golang.org/api/people/v1

或者，您可以创建一个Go模块，然后从go.mod导入依赖项

bazel run //:gazelle -- update-repos -from_file=go.mod

我推荐使用后者。使用go mod init创建一个模块，然后您可以定期运行一个脚本来更新您的依赖项：

# update go.mod
go get -d ./...

# update repos with Gazelle
bazel run //:gazelle -- update-repos -from_file=go.mod
