title: How to access a remote Git repository in Jenkins using aliases?
body: <p><strong>short version</strong></p>
  
  <p>I'm using aliasing to connect my remote Git repositories. It works, but when I add such repository to Jenkins, it cannot access the repository and display the error:</p>
  
  <blockquote>
    <p>Failed to connect to repository : Command "git -c core.askpass=true
    ls-remote -h git@github.com-foo:myaccount/myrepository.git HEAD"
    returned status code 128: stdout: stderr: ssh: Could not resolve
    hostname github.com-foo: Name or service not known fatal: Could not
    read from remote repository.</p>
    
    <p>Please make sure you have the correct access rights and the repository
    exists.</p>

  <p><strong>detailed issue description</strong></p>
  
  <p>In order to <code>commit</code>/<code>push</code> code as different users I use aliasing:</p>
  
  <p><strong><code>C:\Users\myusername\.ssh\config</code></strong></p>
  
  <pre><code>...
  
  #github.com-foo account
  Host github.com-foo
      HostName github.com
      User git
      IdentityFile ~/.ssh/id_rsa_foo
  
  #github.com-bar account
  Host github.com-bar
      HostName github.com
      User git
      IdentityFile ~/.ssh/id_rsa_bar
  
  ...
  </code></pre>
  
  <p>Then instead of</p>
  
  <pre><code>git clone git@github.com:myaccount/myrepository.git
  </code></pre>
  
  <p>I simply use</p>
  
  <pre><code>git clone git@github.com-foo:myaccount/myrepository.git
  </code></pre>
  
  <p>The <code>.ssh</code> directory is accessible from my local VMs as a shared folder, so also use my credentials on the VMs as well.</p>
  
  <p>Everything works.</p>
  
  <p>Now I installed Jenkins on a VM and want to configure the connection to a remote repository stored on GitHub. What I did:</p>
  
  <ol>
  <li><p>Credentials: <code>Jenkins -&gt; Credentials -&gt; [link] Global credentials (unrestricted) -&gt; [radio button] Enter directly -&gt; [textarea] Key -&gt; added -&gt; [button] Save</code>.</p></li>
  <li><p>Git plugin: <code>Jenkins -&gt; Configuration -&gt; [section] Git plugin</code> -- Email and Name set up:</p></li>
  </ol>

  <ol start="3">
  <li>Project Git settings: <code>[project] -&gt; Configuration -&gt; [section] Source Code Management -&gt; [section] Git</code> -- Repository URL and credentials:</li>
  </ol>

  <p>As on the screenshot shown, the connection is failing.</p>
  
  <p><strong>Why does it not work and how to get it working, in order to connect a remote Git repository in Jenkins using aliases?</strong></p>
