1. Govendor Introduction

Golang project dependencies are often obtained using the go get command, for example: Go get Github.com/kardianos/govendor, which will download the dependent package to GOPATH the path.

The common Dependency Package management tool has godep , and govendor so on, after Golang1.5, GO provides GO15VENDOREXPERIMENT environment variables (the Go 1.6 version opens the environment variable by default ), which adjusts the application path search for Go build to be the 当前项目目录/vendor directory mode. In this form, we can implement godep project-dependent management similar to the way it is.

2. Installation and use

2.1. Installation

-u-v github.com/kardianos/govendor

2.2. Use

#进入到项目目录cd /home/gopath/src/mytool#初始化vendor目录govendor init#查看vendor目录[root@CC54425A mytool]# lscommands  main.go  vendor  mytool_test.sh#将GOPATH中本工程使用到的依赖包自动移动到vendor目录中#说明：如果本地GOPATH没有依赖包，先go get相应的依赖包#Go 1.6以上版本默认开启 GO15VENDOREXPERIMENT 环境变量，可忽略该步骤。#通过设置环境变量 GO15VENDOREXPERIMENT=1 使用vendor文件夹构建文件。#可以选择 export GO15VENDOREXPERIMENT=1 或 GO15VENDOREXPERIMENT=1 go build 执行编译export GO15VENDOREXPERIMENT=1

2.3. Description

govendorJust to manage the dependencies of the project, if GOPATH there is no dependency package for the project itself, it needs to be go get downloaded to Gopath and then govendor add +external copied to the vendor directory. Go 1.6 or later the Go15vendorexperiment environment variable is turned on by default .

3. Govendor using commands

By default theinit command adds the "Test"Tag to  theIgnoreList. If using Go1. 5, ensure go15vendorexperiment=1  is Set.

4. Vendor.json

Govendor configuration file, record the list of dependent packages.
