@michaelandrepearce sure! But the only file without the header is the
`additional-spring-configuration-metadata.json`, which I think won't allow
comments. How do you guys add license headers in json files? Also, do we have
some tooling for this type of validation before submitting a PR? For example,
in Apache Camel I run checkstyle to guarantees that the code is ok.---
