I am assuming you tried to follow: https://quarkus.io/guides/building-native-image#creating-a-container-with-a-multi-stage-docker-build

If so, have you followed this:

Before launching our Docker build, we need to update the default .dockerignore file as it filters everything except the target directory and as we plan to build inside a container we need to be able to copy the src directory. So edit your .dockerignore and remove or comment its content.

Yes I did

I tried the process and it works.

Can you perhaps upload a reproducer which demonstrates the failure?

Thanks.

I am not on Windows so I can't really test that setup. Hopefully someone else will be able to.
