File not found when building docker image

[ragaspce]

Hi team,
I am facing an issue where when I build an image which basically say
COPY failed: stat /var/lib/docker/tmp/docker-builder074260150/resources/jasperreports-server-pro-7.1.0-bin/buildomatic/bin/app-server: no such file or directory

I am using the master branch, have jasperreports-server-pro-7.1.0-bin file in resources,
Note: observed that there is no app-server and in the other step where we copy lib from buildomatic/lib, can't find both in the jasperreports-server-pro-7.1.0-bin folder. is it expected??

Please help me resolve this issue :).
