  &lt;groupId&gt;kashier&lt;/groupId&gt;
  &lt;artifactId&gt;Kashier&lt;/artifactId&gt;
  &lt;version&gt;1.0-SNAPSHOT&lt;/version&gt;
  &lt;packaging&gt;pom&lt;/packaging&gt;
  
  &lt;modules&gt;
      &lt;module&gt;AnnotationProcessing&lt;/module&gt;

  <p>Now everything works fine only if i manually create javax.annotation.processing.Processor file in resources directory.
  That means that auto-service is not working and the question is: how do i make it work?</p>
  
  <p>Also i tried to make the same project with java and it works. So i think that the problem is in kotlin-maven-plugin.</p>
