  <p>After I changed to version 1.2.30 in my build-gradle the build worked, but now I have a mismatch between the version used by gradle (1.2.30) and the one bundled into the IDE plugin (1.2.40).</p>
  
  <p>Is there anything I am doing wrong with the new kotlin version ? Or how can I downgrade to the 1.2.30 version ?</p>
  
  <p>Thank you for the attention.</p>
