MTA Deployment has no effect

[#1]

I am trying to deploy my application in SAP Business Applications Studio, by generating the .mtar file from the mta.yaml and then >"Deploy MTA Archive" but the deployment has no effect. Only the old version of the application is available in the SAP BTP Cockpit>subaccount>HTML 5 Applications.

Here is the log:

Skipping deletion of services, because the command line option "--delete-services" is not specified.

According to the log, it did everything right:

Uploading content module "Activity_Sampler_Service_Admin_ui_deployer" in target service "Activity_Sampler_Service_Admin_html_repo_host"... 
Deploying content module "Activity_Sampler_Service_Admin_ui_deployer" in target service "Activity_Sampler_Service_Admin_html_repo_host"... 

So I can only point you in a few directions. A possible cause might be that you deployed a older mtar archive or that build process didn't pick up the latest web app and put it in the archive. Or maybe this is just a caching issue.

UPDATE: The reason why the deployment was unsuccessful is that the .zip file was not updated during build.
The following code was added to xs-app.json:

{ "source": "^/resources/(.*)$", "target": "/resources/$1", "authenticationType": "none", "destination": "ui5" }, { "source": "^/test-resources/(.*)$", "target": "/test-resources/$1", "authenticationType": "none", "destination": "ui5" },
