title: Pulling a specific version with git
body: <p>I need the source code from a specific version of a project (The <a href="https://github.com/SonarSource/sonarqube" rel="noreferrer">SonarQube</a> project), but I can't figure out how to pull it from git.</p>
  
  <p>I've added the repo as a remote (<code>git add remote origin</code>) and pulled the latest version from the master branch, but that is not the version I need.</p>
  
  <p>I know the commit I need is <code>d25bc0e</code>, but when I try "<code>git fetch origin master d25bc0e</code>" I get the error "<code>fatal: couldn't find remote ref d25bc0e</code>".</p>
  
  <p>It could be I'm doing something very wrong, I am not very experienced with Git.</p>
