本文介绍了如何解决Android Studio 3.0升级后使用ButterKnife 7.0.1版本时出现的错误。通过修改app的build.gradle文件中的配置，可以有效地解决该问题。

在Android开发时，将Android Studio升级至3.0之后，使用ButterKnife 7.0.1版本时出现如下错误：

Error:Execution failed for task ':xxx: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.

解决方法如下：
在app的build.gradle中添加如下代码：

android {
    ......

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

    ......
}

由此便可解决如上异常错误。
