UATHelper: Packaging (Android (ETC2)): Gradle may disable incremental compilation as the following annotation processors are not incremental: lifecycle-compiler-2.0.0.jar (androidx.lifecycle:lifecycle-compiler:2.0.0).
UATHelper: Packaging (Android (ETC2)): 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.
