title: Using a pipeline variable for a variable group in YAML?
body: <p>I would like to use a common pipeline definition for our solutions. Using variables, I would like to specify solution specific settings. This works, except for a variable group.</p>
  <p>I would like to use the pipeline definition in my variable group definition.
  For example:</p>
  <blockquote>
  <ul>
  <li>group: $(Build.DefinitionName).Dev</li>
  </ul>
  </blockquote>
  <p>But that does not work. Another option would be to use a pipeline variable, but neither does work:</p>
  <blockquote>
  <ul>
  <li>group: $(buildDefinitonName).Dev</li>
  <li>group: {{ variables.buildDefinitonName }}.Dev</li>
  </ul>
  </blockquote>
  <p>What does work is a parameter, but I do not want to specify it for each run.</p>
  <blockquote>
  <ul>
  <li>group: ${{ parameters.buildDefinition }}.Dev</li>
  </ul>
  </blockquote>
