There are 3 Tag related CLI arguments

--listTags

--includeTags

--excludeTags

As I understand it Tags can be linked to rules and MTA should be able to apply those  --includeTags --excludeTags to refine which rules are selected for execution.

The --listTags output is needs t be checked as cloud-readiness is listed but the tag in the openshift rules is actually just cloud

The --excludeTags seems to work, so this command excluded some cloud-readiness rules from firing

./mta-cli --input ../samples/jee-example-app-1.0.0.ear --output $HOME/MTA_Output/jee_example_app_tags --target eap:7 --target cloud-readiness --excludeTags cloud

However no MTA output is generated if the --includeTags parameter is used.
