slim package includes dot_underscore files and appinspect fails because of them

[czervos]

I am developing my splunk app on a mac OS X system.

As a result the static directory contains along with the app*.png files the corresponding ._app*.png files.

When I slim package my app the tar.gz archive contains the dot_underscore files and as a result the appinspect fails the package with

A default value of 25 for max-messages will be used.
Splunk app packaging standards These checks validate that a Splunk app has been 
correctly packaged, and can be provided safely for package validation. 
    Check that the extracted Splunk App does not contain any directories or 
    files that start with a ., or directories that start with __MACOSX.

        FAILURE: A prohibited file or directory was found in the 
            extracted Splunk App: static/._appLogo.png 

I tried removing the dot underscore files prior to packaging the app by issuing

dot_clean  appname/static/

but when I repackage the app the new resulting archive still includes them. Has anyone else run into this problem and if yes how did you get around it?

TIA

COPYFILE_DISABLE=true should always be in your environment when packaging tarballs on macOS.
