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 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.
在build.gradle（app）下增加如下配置
android {
...
defaultConfig {
...
javaCompileOptions {
annotationProcessorOptions {
includeCompileClasspath = true
}
}
}
}
具体如下:
android {
compileSdkVersion 23
buildToolsVersion '27.0.3'
defaultConfig {
applicationId "com.whatled.demo"
minSdkVersion 11
targetSdkVersion 23
versionCode 1
versionName "1.0"
javaCompileOptions {
annotationProcessorOptions {
includeCompileClasspath = true
}
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
}
