[~xiaoping.huang] wow - what a big project. Unfortunately I'm unable to build it locally, but feel free to go ahead with the following change (attached as RAT-531.patch) in your central pom.xml and run:

mvn apache-rat:rat

afterwards.

It might speed up your build to include the Maven wrapper in your project:
https://maven.apache.org/tools/wrapper/
and use a fixed Maven version during the build of your project.
