The enhancement

What is the problem this solves or benefit it gives

Spring boot archives require library files to be stored uncompressed so they can be loaded. By allowing the recompression of Java archives with zero compression, we can support these applications.

Proposed solution

Expose an option in the Java archive deployment step to allow the recreated artifact to not use compression.

Mockup

Workarounds

Custom scripting for the process of unpacking a file, processing any template files or injecting variables, and then repacking could be done with a deploy a package step.
