Docker COPY only copies one sub-directory, not whole build context

I have create a dummy project with Quarkus' Maven archetype in Java. I want to copy the whole build context into my Docker container.

When I perform ls -al in the current directory I get this result:

drwxr-xr-x  12 my.user  staff    384 19 Aug 15:57 .
drwxr-xr-x  12 my.user  staff    384 19 Aug 15:39 ..

drwxr-xr-x   4 my.user  staff    128 19 Aug 15:39 src
drwxr-xr-x  15 my.user  staff    480 19 Aug 15:40 target

This is my Dockerfile:

FROM maven:3-jdk-11-slim
WORKDIR /home/mvn
COPY ./ .
RUN ls -al
RUN mvn verify

Unfortunately only the target folder gets copied. This is the resulting output from docker build .:

The Quarkus Maven archetype added a .dockerignore file. In it only the target folder was not excluded from Docker. Hence only the target folder has been copied.
