I believe it will improve FileVault usage if we make it easier for users to consume the software.
One way to achieve this is to publlish binary artifacts.
Docker makes this easy to.
I've published patches in a PR on Github https://github.com/apache/jackrabbit-filevault/pull/25 .
Docker file contains a multi-stage docker build:
Stage 1: builds FileVault binary using official maven openjdk image
Stage 2: Creates a FileVault image that can be published via automated builds on docker hub.
