When importing a project into studio, the following error will occasionally be reported
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.
I also post a picture of the error report here. It’s a direct screenshot. It doesn’t look very clear. You can double-click to open the picture.
Modification :
Add the following part to the app's build.gradle:
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.sxwz.myapplication"
minSdkVersion 18
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
//TODO 添加部分
javaCompileOptions {
annotationProcessorOptions {
includeCompileClasspath true
}
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
