Update Manifest inside JAR

Create a file, manifest-attributes.txt, and add new properties, e.g.

Class-Path: additional.jar

Then

jar umf manifest-attributes.txt test.jar

If the JAR file is in a container, then copy manifest-attributes.txt into a volume.

docker exec my-container jar umf /bindmount/manifest-attributes.txt test.jar
