title: mapstruct and gradle configuratoin issue in Intellij IDEA
body: <p>I have a project using gradle, and have mapstruct as one of dependency. everytime I tried to build project, it failed. I guess it is because Mapstruct will generate impl class that gradle was not able to find. Can anyone help me how to configure this in intellij IDEA?</p>
  
  <p>Thanks</p>
