What is the significance of the POM file that Maven places in a JAR file, is it used by anything?

Question

When Maven builds a JAR file, it places the module\'s POM file inside (seemingly in the directory /).

When I build a JAR file from A

Answer 1

The pom.xml inside JAR is designed for following purposes,

1. Automatic dependency resolution.
2. Deployment of JAR. It's possible to extract pom.xml from JAR automatically.
3. Integrity check by repository (JAR matches POM).

I don't know if any of these features are implemented anywhere. You can ignore it for sure.
