The update to Java 11 is a breaking change for users on older JVMs. This requirement is currently inconsistent with the build instructions in the 'How to Build' section (line 70), which should also be updated to specify JDK 11. Additionally, Android developers will need to enable core library desugaring to support Java 11 APIs on devices with API levels below 30.
