androidstudio3.+版本使用butterknife注解插件,无法加载依赖包

下面这个异常：给了两种解决方式：

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-5.1.1.jar (com.jakewharton:butterknife:5.1.1)
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.

方法一： 在app.builder文件的defaultConfig下添加

  javaCompileOptions {
            annotationProcessorOptions {
                includeCompileClasspath = true
            }
        }

但是官方也给出了提示，说在以后的版本中可能会删除，不推荐使用这种方式，推荐使用 方法二>>>>>>>>>>>>>>>>>>>

方法二： 直接复制覆盖掉原来的所有关于butterknife依赖

    implementation 'com.jakewharton:butterknife:8.6.0'
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.6.0'
