> 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-compiler-8.5.1.jar (com.jakewharton:butterknife-compiler:8.5.1)
- auto-service-1.0-rc2.jar (com.google.auto.service:auto-service:1.0-rc2)
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.
解决办法:
javaCompileOptions {
annotationProcessorOptions {
includeCompileClasspath =
true
}
}
