production docker file failed at copying pserver to /usr/bin

[putcn]

I was using paddle_build.sh to generate dockerfile in build dir, my build was conducted with WITH_GOLANG=OFF. which means paserver and master bin will not be generated, but looks when I run paddle_build.sh dockerfile, it still generates the line as follows:

ADD go/cmd/pserver/pserver /usr/bin/
ADD go/cmd/master/master /usr/bin/

which fails the build process.

I think this issue was fixed in non-paddle_build.sh script.

please see #10043 for reference.
