title: Can't get the delegate of the gradle IncrementalProcessingEnvironment in STS 4
body: <p>Since I installed the Spring Tool Suite 4 I get on every class definition the warning</p>
  
  <pre><code>Can't get the delegate of the gradle IncrementalProcessingEnvironment.
  </code></pre>
  
  <p>I do not use gradle for building my project but maven. So, why is there a need for the gradle IncrementalProcessingEnvironment? How can I get rid of these warnings?</p>
