考虑一个仓库repo，github.com/myacct/sandbox其ji目录位于顶部：
$ 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，直接来自文档。我已经跑了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"],
)
部门看起来不错，这就是我要导入的内容one.go。
这是失败的方式：
$ 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
INFO: Elapsed time: 0.087s

我发现文档实际上非常详尽。
无论如何，您需要运行update-repos。您可以运行一次性命令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，然后从导入依赖go.mod：
bazel run //:gazelle -- update-repos -from_file=go.mod
我建议后者。使用创建一个模块，go mod init然后可以定期运行一个脚本来更新依赖项：
# update go.mod
go get -d ./...
# update repos with Gazelle
bazel run //:gazelle -- update-repos -from_file=go.mod
