android studio 报错 com.jakewharton:butterknife:6.1.0

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-6.1.0.jar (com.jakewharton:butterknife:6.1.0)
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.

 

解决办法：

 

android {
    defaultConfig {
        ...
        javaCompileOptions{
            annotationProcessorOptions {
                includeCompileClasspath true
            }
        }
    }
    ...
}
