Manifest files

Question

Manifest files

I'm sorry in advance that I can’t give the exact code, because I don’t have it now. However, I ran into a problem trying to pack my project in a jar. I used the maven build plugin in my pom.xml to collect all the dependencies and the jar of the project in one place. But now I need all these dependency banks to have their own manifest file. Can I implement some Maven properties in some way? Now, the only solution I came up with is to use the Maven shade plugin and create uber-jar, but the problem is that some dependencies have user manifests (like Spring framework) that get lost and only one manifest for uber-jar is created. Is there any way to say maven for unpacking dependencies, edit manifestEntries and assemble them again and put together with the project bank in zip?

In short: basically, what I want to know is whether it is possible to somehow modify the file inside one of the dependency containers or in all bars with a dependency at once? Say my project has a dependency on spring - beans. Now I would like to modify a specific file inside spring - beans.jar, in particular manifest.md, before collecting them into a single ZIP file, which should contain project.jar and spring - beans.jar (with manifest.md changed). I think something like this is possible with the maven antrunner plugin?
