title: PowerMockito gives NoClassDefFoundError
body: <p>I'm trying to set up a unit test with Mockito and PowerMockito, but it throws: </p>
  
  <blockquote>
    <p>Exception in thread "main" java.lang.NoClassDefFoundError:
    org/mockito/exceptions/Reporter</p>
  </blockquote>
  
  <p>whenever I try to run a test. These are my dependencies:</p>
  
  <pre><code>testCompile 'org.mockito:mockito-core:2.8.9'
  testCompile 'org.powermock:powermock-api-mockito2:1.6.5'
  testCompile 'org.powermock:powermock-module-junit4:1.7.4'
  </code></pre>
  
  <p>Does anyone know how to fix it?</p>
