Building Docker image

Hi all,
I am trying to build a docker image for my Lucee project by using: GitHub - isapir/lucee-docker: Build Custom Lucee Docker Images
Unfortunately I am getting the following error:
Error opening zip file or JAR manifest missing : /srv/www/catalina-base/lib/lucee-external-agent.jar
The jar file under: isapir\lucee-docker\resources\catalina-base\lib it is 2KB

Could you help me, please?

If there is another way for containerizing the app, that will help as well.

Quick update, I hope it would be helpful for someone. The repository is working normaly on Mac, but hte dockerfile is failing on Windows.
