1. Android Studio 編譯時報錯如下:
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.
2. 解決方式
在 app 項目目錄中的 build.gradle 文件中,找到 defaultConfig 並在這個方法裏面添加如下代碼:
javaCompileOptions {
annotationProcessorOptions {
includeCompileClasspath true
}
}
