title: "Execution failed for task: ':app:javaPreCompileDebug' " in Android Studio 3.0.1
body: <p>I get the following errors when trying to execute my project:</p>
  
  <blockquote>
    <p>Error:Execution failed for task ':app:javaPreCompileDebug'.</p>
    
    <blockquote>
      <p>Annotation processors must be explicitly declared now.  The following dependencies on the compile classpath are found to contain
      annotation processor.  Please add them to the annotationProcessor
      configuration.
          - butterknife-7.0.1.jar (com.jakewharton:butterknife:7.0.1)   Alternatively, set
      android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath
      = true to continue with previous behavior.  Note that this option is deprecated and will be removed in the future.   See
      <a href="https://developer.android.com/r/tools/annotation-processor-error-message.html" rel="nofollow noreferrer">https://developer.android.com/r/tools/annotation-processor-error-message.html</a>

  <p>Please don't mark this question as duplicate as other question regrading this, here, is for lombok, which I'm not using.</p>
