Android Studio3.0 Error:Execution failed for task ':app:javaPreCompileDebug' 错误

报错信息

Error:Execution failed for task ':app:javaPreCompileDebug'.

> 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 https://developer.android.com/r/tools/annotation-processor-error-message.html for more details.

解决方法

 //在app.gradle添加如下配置就好了

 javaCompileOptions { annotationProcessorOptions { includeCompileClasspath = true } }
