title: Cocoapods - Specify Source Repo Username
body: <p>Using Cocoapods v0.34.4</p>
  
  <p>My Podfile contains the following</p>
  
  <pre><code>source 'https://bitbucket.org/MyRepo/My-podspecs.git'
  source 'https://github.com/CocoaPods/Specs.git'
  </code></pre>
  
  <p>When I run <strong>pod install</strong> I need to specify a username/password for my bitbucket account. This is fine when I am running locally, however I am also running this as part of a Continuous Integration build with XCode Server and XCode 6.
  On XCode Server the <strong>pod install</strong> command fails because it cannot access bitbucket without my credentials. </p>
  
  <p>Is it possible to add my credentials to the Podfile or any other way to tell Cocoapods the credentials for the bitbucket source repo?</p>
