title: How to get codecov.io to post coverage reports to bitbucket pull request comments
body: <p>I am trying out using codecov.io with BitRise and BitBucket. I am able to get code coverage reports from my pull requests posted to CodeCov.io, but not to the bitbucket pull request comments. </p>
  
  <p>I have added a codecov.yaml file to the repo, which looks like this:</p>
  
  <pre><code> comment:
    layout: "reach, diff, flags, files"
    behavior: default
    require_changes: false  # if true: only post the comment if coverage changes
    require_base: no        # [yes :: must have a base report to post]
    require_head: no       # [yes :: must have a head report to post]
    branches: null
  </code></pre>
  
  <p>And I have also set up a new bitbucket user with write access to the repo, that I have also logged into codecov.io with, and I have set this user as the 'codecov bot' by editing the Team.yaml file as follows:</p>
  
  <pre><code>codecov:
      bot: codecovbot
  </code></pre>
  
  <p>Is there anything else I need to do to get this working?</p>
