同個項目換了個機器報了以下錯誤：
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-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.
解決辦法：
在app的build中
android {...
defaultConfig {
...
//添加如下配置就OK了
javaCompileOptions { annotationProcessorOptions { includeCompileClasspath = true } }
}
...
}
