In a java project I would like to create a zip archive with a file under src/main/resources and then include that zip in the generated jar artifact.

*The ZIP archive is an AWS lambda implementation used only in tests, hence I'd like to share it across multiple sub-projects with minimum effort.

The structure is:

.
├── src
│   └── main
│       └── resources
│           └── index.js
└── pom.xml

and I'd like the output to be:

.jar
└── function.zip

I've tried using the assembly plugin to generate the ZIP archive but then I couldn't figure out how I can add it in the JAR package. Is there a plugin that combines these actions in that order?
