Github Workflow Maven Caching - Multi-Module Project

Question

I am working on integrating Sonar for a multi-module Maven Project which has 3 modules. I need to speed up the Maven Build Process by enabling caching. Sonar Reports are working correctly but still the caching is not happening. Below here find the Github Workflow File with the configurations which I want to cache the dependencies only relevant to the cloud-pci-ui module
