在rebuild后出现如下提示

Gradle may disable incremental compilation as the following annotation processors are not incremental: auto-service-1.0-rc5.jar (com.google.auto.service:auto-service:1.0-rc5).
Consider setting the experimental feature flag android.enableSeparateAnnotationProcessing=true in the gradle.properties file to run annotation processing in a separate task and make compilation incremental.
