It has 5 modules like android, angular-client, design-impl, hub-spot-email and lastly, loan-calc-service. The moduels hub-spot-email, and loan-calc-service are the Spring boot app. When I tried to build at the first time, I get the pop-up to set the output path for the project,

Note

So far I only managed to set the Android SDK for the project.
