+title: Git Clone via SSH using Jenkins on Windows
+author: Matt Robbins

+---
+
+This blog post is nothing revolutionary but more of a note to self so that I never have to learn this painful lesson again!
+
+My current team has Windows specific CI dependencies, hence I had no choice but to setup our Jenkins instance on Windows.  The cleanest way to do this is to use the [Jenkins Installer](https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+as+a+Windows+service) which installs Jenkins as a Windows Service.
+
+That works fine, but of course the first challenge you face is cloning your Git repo over SSH (the default for the Jenkins Git plugin).
+
+I'll assume you have done the following:
+
+* Installed [Git Client](https://code.google.com/p/msysgit/downloads/list)
+* Created [SSH Keys](https://help.github.com/articles/generating-ssh-keys#platform-windows) and ensured that you can successfully clone a repo from your Git Bash (running as current user).
+
+    Note: In theory you should not use passwordless keys as anybody obtaining your key will have access to your account.  However for Jenkins you cannot have a password as the Job would hang when attempting to clone.  From Git Bash this problem is solved using [ssh-agent](https://help.github.com/articles/working-with-ssh-key-passphrases#platform-windows) but this won't work in Jenkins as we are using the Git plugin and not the shell.
+
+    Bottom line - for Jenkins use a passwordless key - you can mitigate the risk by having a dedicated Jenkins Git User and only allowing them pull access.
+
+* Set up the Git plugin in Jenkins via 'Manage Jenkins' and point it to the Git cmd file on the system, as in the screenshot below:
+
+![jenkins_git_plugin](/images/jenkins_git_plugin.png)
+
+
+Now we get to the tricky part.  When Jenkins runs as a Windows Service it does not run under a normal user account, it runs under the "Local System Account".  Hence even though you have Git Clone working as the current user it will fail in Jenkins.
+
+To solve this problem we need to put our private ssh key in the correct location for the Local System Account.
+
+First of all we need to find out where this user's home directory is, since it will not exist under C:\Users...
+
+* Download [PSTools](http://download.sysinternals.com/files/PSTools.zip)
+* Extract to a conventiant location and using a command prompt navigate to that location (or add to path if you prefer)
+* Start the PsExec tool by running:
+
+{% highlight console %}
+PsExec.exe -i -s cmd.exe
+{% endhighlight %}
+
+* Now we need to find out where this user's home directory is:
+
+{% highlight console %}
+echo %userprofile%
+{% endhighlight %}
+
+* For me this location was:
+
+{% highlight console %}
+C:\Windows\system32\config\systemprofile
+{% endhighlight %}
+
+* Now you can open Git Bash within this shell by running the following command:
+
+{% highlight console %}
+C:\Program Files (x86)\Git\bin\sh –login –i
+{% endhighlight %}
+
+* You can copy your existing private key into the correct location for the Local System User, for me this was something like the following:
+
+{% highlight console %}
+cd ~
+cp /c/Users/matt/.ssh/id_rsa ~/.ssh/
+{% endhighlight %}
+
+* Finally you can test that you can successfully authenticate to Github as the Local System User:
+
+{% highlight console %}
+ssh -T git@github.com
+{% endhighlight %}
+
+* If all is successful you should see the usual message:
+
+{% highlight console %}
+Hi username! You've successfully authenticated, but GitHub does not provide shell access.
+{% endhighlight %}
+
+
+All that's left to do now is test from Jenkins...Huzzah!
