Why do I have problems whith 'com.jakewharton:butterknife:7.0.1' in Android Studio 3.0?
提问by Héctor DlaCruz III
I have the following problem when I run the 'app' (Android studio emulator):
我在运行“应用程序”（Android Studio 模拟器）时遇到以下问题：
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.

try this ,you need to add the annotation along with ButterKnife library..
试试这个，你需要和 ButterKnife 库一起添加注释..
Butterknife library
黄油刀图书馆
