Why GIT Plugin in Jenkins is not able to connect to the GIT Repository?
提问by ANIL
I am trying to pull the code form GIT using GIT Plugin Jenkins and the job is running on a slave machine.
我正在尝试使用 GIT 插件 Jenkins 从 GIT 中提取代码，并且该作业正在从属计算机上运行。
MASTERsystem has http_proxy=mycom.domain.com:80
MASTER系统有 http_proxy=mycom.domain.com:80
and in SLAVEsystem there is no http_proxydefined.
并且在SLAVE系统中没有http_proxy定义。
Whenever I am doing git clone locally in the SLAVEmachine it works perfectly, however from Jenkins I haven't been successful.
每当我在SLAVE机器上本地执行 git clone 时，它都能完美运行，但是在 Jenkins 中我并没有成功。
It is throwing the following error:
它抛出以下错误：
Building remotely on SLAVE in workspace /data/test

Is it because the MASTERsystem trying to set http proxy which is not present in the SLAVEsystem?
是不是因为MASTER系统试图设置系统中不存在的http代理SLAVE？
If yes, how to prevent it?
如果是，如何预防？
Or, is there something else I am missing?
或者，还有什么我想念的吗？

Turned out it was a proxy issue.
原来是代理问题。
While pulling the code from GIT using Jenkins it was setting the http_proxyto mycom.domain.com:80(MASTERmachine proxy) and this proxy was not required in the SLAVEmachine.
当使用从詹金斯GIT拉动代码它被设置http_proxy到mycom.domain.com:80（MASTER机代理），并在未要求该代理SLAVE机。
So, I just added the GIT URL to No Proxy Host section (Manage Jenkins -> Manage Plugins -> Advanced -> HTTP Proxy Configuration -> Added GIT URL in No Proxy Host field)in Jenkins and now it is working fine.
所以，我刚刚将 GIT URL 添加到(Manage Jenkins -> Manage Plugins -> Advanced -> HTTP Proxy Configuration -> Added GIT URL in No Proxy Host field)Jenkins 的No Proxy Host 部分，现在它工作正常。
回答by Ala Eddine JEBALI
Before pulling the project, try to set the HTTP proxy in global configuration:
在拉项目之前，尝试在全局配置中设置HTTP代理：
$> git config --global http.proxy http://mycom.example.com:80
$> git config --global http.proxy http://mycom.example.com:80
If you need to provide a username and a password for your proxy, you can use:
如果您需要为代理提供用户名和密码，您可以使用：
$> git config --global http.proxy http://example.com\\<yourUsername>:<yourPassword>@<yourProxyServer>:80
$> git config --global http.proxy http://example.com\\<yourUsername>:<yourPassword>@<yourProxyServer>:80

Today i also set up the jenkins with git repository, worked for me, hope this helps,
今天我还用 git 存储库设置了 jenkins，对我来说有效，希望这有帮助，
To connect git with jenkins do following steps :
要将 git 与 jenkins 连接，请执行以下步骤：
STEP 1. After successfull installation of plugins create a new job like this:
第 1 步。成功安装插件后，创建一个像这样的新工作：
1.create a Job name
1.创建作业名称
2.checked the radio button of Build a maven software project
2.勾选Build a maven software project的单选按钮
3.click OK
3.点击确定
STEP 2. Now checked the radio button for Git enter the uri of your git repository.
第 2 步。现在选中 Git 的单选按钮，输入您的 git 存储库的 uri。
STEP 3. If you will see the error like
第 3 步。如果你会看到这样的错误
Failed to connect to repository : Command "git ls-remote -h [email protected] HEAD" returned status code 128: stdout: stderr: fatal: '[email protected]' does not appear to be a git repository fatal: The remote end hung up unexpectedly
无法连接到存储库：命令“git ls-remote -h [email protected] HEAD”返回状态代码 128：stdout：stderr：fatal：'[email protected]' 似乎不是 git 存储库致命：远端意外挂断
You have to do some more configuration:
你必须做一些更多的配置：
1.Go to to the terminal
1.前往终端
2.Run this command : sudo visudo
2.运行此命令：sudo visudo
3.Add %jenkins ALL=NOPASSWD: ALL in this file where sudo previlage is defined.and close the file.
3.在此文件中添加 %jenkins ALL=NOPASSWD: ALL 定义 sudo previlage。并关闭文件。
4.login as jenkins user via command : sudo su jenkins
4.通过命令以jenkins用户身份登录：sudo su jenkins
5.Create a .ssh directory in the jenkins home directory.
5.在jenkins家目录下创建一个.ssh目录。
6.create the public private key pair like this.
6.像这样创建公钥私钥对。
Generating SSH Keys:
生成 SSH 密钥：
1:Check for SSH keys
1：检查SSH密钥
First, we need to check for existing ssh keys on your computer. Open up Terminal and run:
首先，我们需要检查您计算机上现有的 ssh 密钥。打开终端并运行：
cd ~/.sshChecks to see if there is a directory named ".ssh" in your user directory
cd ~/.ssh检查你的用户目录中是否有名为“.ssh”的目录
If it says "No such file or directory" go to step 2. Otherwise, you already have an existing keypair, and you can skip to step 3.
如果显示“没有这样的文件或目录”，请转到第 2 步。否则，您已经有一个现有的密钥对，您可以跳到第 3 步。
2: Generate a new SSH key
2：生成新的SSH密钥
To generate a new SSH key, enter the code below. We want the default settings so when asked to enter a file in which to save the key, just press enter.
要生成新的 SSH 密钥，请输入以下代码。我们需要默认设置，因此当要求输入保存密钥的文件时，只需按 Enter。
ssh-keygen -t rsa -C "[email protected]"
ssh-keygen -t rsa -C "[email protected]"
Creates a new ssh key, using the provided email as a label Generating public/private rsa key pair. Enter file in which to save the key (/home/you/.ssh/id_rsa): Now you need to enter a passphrase or file.press enter without to write any thing.
创建一个新的 ssh 密钥，使用提供的电子邮件作为标签生成公共/私有 rsa 密钥对。输入要保存密钥的文件 (/home/you/.ssh/id_rsa)：现在您需要输入密码或文件。按 Enter 键无需写任何内容。
Which should give you something like this:
这应该给你这样的东西：
Your identification has been saved in /home/you/.ssh/id_rsa.
您的身明已保存在/home/you/.ssh/id_rsa 中。
Your public key has been saved in /home/you/.ssh/id_rsa.pub.The key fingerprint is:
您的公钥已保存在/home/you/.ssh/id_rsa.pub 中。关键指纹是：
01:0f:f4:3b:ca:85:d6:17:a1:7d:f0:68:9d:f0:a2:db [email protected]
01:0f:f4:3b:ca:85:d6:17:a1:7d:f0:68:9d:f0:a2:db [email protected]
3: Add your SSH key to GitHub
3：将您的 SSH 密钥添加到 GitHub
Go to your Account Settings
转到您的帐户设置
4 :Under Source Management tag,
