The last line should not end with && \ - not sure if it is the problem but it sure is a problem.
This is a terrible practice. As you can already see, its hard to debug. Create your files normally, and just COPY them to the image instead of creating them with an awkward chain of shell commands.

To have less intermediate images it is better to have less `RUN` steps. But @DannyB is right, for copy files please use `COPY`. – Wie May 17 '19 at 08:24
