異常特徵:
編譯時候報錯,如下:
* What went wrong:
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.
原因分析:
編譯時缺少了一些配置參數。
解決方案:
在app的build.gradle文件的defaultConfig加入javaCompileOptions配置,即可
defaultConfig {
applicationId "com.atguigu.shoppingmall"
minSdkVersion 14
targetSdkVersion 24
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
//加入javaCompileOptions配置
javaCompileOptions {
annotationProcessorOptions {
includeCompileClasspath = true
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
