title: CodeClimate report in GitLab for c++ not showing
body: <p>I am trying to activate the code climate report for merge requests pipelines in GitLab. The CodeClimate analyser is running but there are not shows any warnings when I add some bad code. There might be some configuration which I have missed.</p>
  
  <p>I have added the following to my .gitlab-ci.yml file in the project rot folder:</p>
  
  <pre><code>include:
      - template: Code-Quality.gitlab-ci.yml
  </code></pre>
  
  <p>And I have added the .codeclimate.yml file looks like this:</p>
  
  <pre><code>plugins:
    cppcheck:
      enabled: true
      config:
        check: all
        language: c++
        stds:
          - c++14
          - c++17
  </code></pre>
  
  <p>The build job completes with the following lines at the end of the log:</p>
  
  <pre><code>f47a75dcba39: Pull complete

  <p>What could be wrong here, since the merge request doesn't show any CodeClimate report?</p>
  
  <p>In GitLab I have created one merge request with the configuration change (merging into master). And one merge request with some bad code, based on the first merge request with the configuration (merging into master).</p>
  
  <p>The bad code:</p>
  
  <pre><code>int non_used_int;
  
  int non_initialized_int;
  
  int dummy = non_initialized_int;
  
  
  
  
  
  // empty for loop
  for (int i=0; i&lt;100; i++) {
  
  }
  </code></pre>
  
  <p>And a final note: I am using the shared GitLab runners provided by GitLab.</p>
