title: JaCoCo: missing classes directory
body: <p>I am fairly new to JaCoCo and I am having trouble generating my code coverage report. </p>
  
  <p>This is my project structure:</p>
  
  <p><img src="https://i.stack.imgur.com/2sulK.png" width="300"></p>
  
  <p>My integration tests live within the "...-integration-tests" module. When I build my project using mvn I get the following in my logging:</p>
  
  <pre><code>[INFO] Skipping JaCoCo execution due to missing classes directory: ...-integration-tests\target\classes
  </code></pre>
  
  <p>This is true because my compiled code is only available in the target>classes of the corresponding module.</p>
  
  <p>What is the best way to make this working? Thanks in advance!</p>
