title: Kotlin-allopen for android
body: <p>Is it possible to use kotlin-allopen gradle plugin for android testing with mockito? </p>
  
  <p>I've tried to add kotlin-allopen plugin to my build.gradle and define the annotation. </p>
  
  <pre><code>buildscript {
     ext.kotlin_version = '1.0.6'
  
     dependencies {
         classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
         classpath "org.jetbrains.kotlin:kotlin-allopen:$kotlin_version"
     }
  }
  
  apply plugin: 'com.android.application'
  apply plugin: 'kotlin-allopen'
  apply plugin: 'kotlin-android'
  
  allOpen {
      annotation("com.mycompany.OpenForTest")
  }
  </code></pre>
  
  <p>And these for annotation itself</p>
  
  <pre><code>annotation class OpenForTest
  </code></pre>
  
  <p>It's not working for me. Maybe I miss something?</p>
