Please describe the bug 🐞

I checked out main and used docker-used maven (https://hub.docker.com/_/maven) to run mvn clean package but it fails with this error:

[ERROR] Failed to execute goal org.apache.rat:apache-rat-plugin:0.16.1:check (default) on project xtable: Too many files with unapproved license: 624 See RAT report in: /usr/src/mymaven/target/rat.txt -> [Help 1]

To reproduce:

git checkout main
docker run -it --rm --name my-maven-project -v "$(pwd)":/usr/src/mymaven -w /usr/src/mymaven maven:3.8-openjdk-11-slim mvn clean package

The last part of the build output is:
