最近android studio 升級了缘揪，對于以前的項目編譯后出現(xiàn)了下面的錯誤证逻，
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.
解決方法就是在gradle 里的 android? --》defaultConfig 里添加如下設置
