【Bug】android Studio使用butterknife报错的解决方法

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
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.

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

javaCompileOptions {
annotationProcessorOptions {
includeCompileClasspath = true
}
}
