前置条件：安装 java、go、xcode、bazel、vscode、beego，安装过程略。
笔者环境如下：
Microsoft Windows [版本 10.0.17134.228]
- - -
go version go1.11.1 windows/amd64
- - -
Python 2.7.15 (v2.7.15:ca079a3ea3, Apr 30 2018, 16:30:26) [MSC v.1500 64 bit (AMD64)] on win32
- - -
java version "1.8.0_151"
Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)
- - -
bazel version

首先，我们拿 Beego 来练手，先在本地新建一个 Begoo 项目跑起来：
git clone -b bazel https://gitlab.com/higkoohk/Mash && cd Mash
govendor init
govendor add +external
cp -rfv conf views tests/
在Gitlab上配置CI/CD后提交代码触发自动构建，成功：
接下来体验一下 Bazel 的效果：
#使用Gazelle自动生成Bazel配置文件
go get -u github.com/bazelbuild/bazel-gazelle/cmd/gazelle
gazelle -go_prefix gitlab.com/higkoohk/Mash
#或者用Bazel来驱动Gazelle来生成编译配置
cat << _EOF > BUILD.bazel
load("@bazel_gazelle//:def.bzl", "gazelle")
# gazelle:prefix gitlab.com/higkoohk/Mash
gazelle(name = "gazelle")
_EOF
bazel run //:gazelle
生成 gitlab.com/higkoohk/Mash/BUILD.bazel 文件如下：
load("@io_bazel_rules_go//go:def.bzl", "go_binary", "go_library")
go_library(
name = "go_default_library",
srcs = ["main.go"],
importpath = "gitlab.com/higkoohk/Mash",
visibility = ["//visibility:private"],
deps = [
"//vendor/github.com/astaxie/beego:go_default_library",
"//routers:go_default_library",
],
)
go_binary(
name = "Mash",
embed = [":go_default_library"],
visibility = ["//visibility:public"],
)
成功开启build //...模式：
附加信息：
苹果系统开启vscode之go的debug功能需要xcode的命令行工具，使用 xcode-select --install 可能由于网络原因执行失败：
可以通过苹果的开发者网站 https://developer.apple.com/download/more/ 下载，手动安装：
