Add "Automatic-Module-Name" to JAR Manifest

[brcolow]

Currently when trying to use aws-xray-sdk-java on a modular Java project one gets the following error:

 (package com.amazonaws.xray.interceptors is declared in the unnamed module, but module my.module does not read it)

Even though this project is not modular you can use the Automatic-Module-Name fallback. Please see:

Here is how it is used in AWS aws-sdk-java-v2, for example: https://github.com/aws/aws-sdk-java-v2/search?q=Automatic-Module-Name

Thank you.

Hi @brcolow,
I think we'd be open to adding this to support consumers that have modular java projects. If you're able to submit a PR to add this annotation we'd happily take a look!
