Dockerfile / Build Fails

[cfarsbot]

Unfortunaly the Dockerfile fails, when executing ./build.sh

I constantly getting the following error

Step 5/8 : COPY ${DEPENDENCY}/BOOT-INF/lib /app/lib
COPY failed: file not found in build context or excluded by .dockerignore: stat build/dependency/BOOT-INF/lib: file does not exist

The same happens for all the other COPY commands of the Dockerfile.
It seems like, that the whole implementation is somewhat broken.

After removing all COPY Commands the build will be shown as Successfully.
But the Container will not run, because the jdbc.Application file is missing.
