I came with a very weird issue with IntelliJ, I have spent many hours now and haven't found a solution to it. I have multiple Spring Boot applications where the properties are inside an application.yml file and all of them were working completely fine. After restarting my environment, without making any change, they all started complaining about not finding the properties inside their respective yml files. The @Value Spring annotations and even the simple server.port configurations were ignored, which made me think that the issue is that the application.yml files are not being read anymore. As an experiment I added an application.properties to one of my apps and it worked! I know it is not a SpringBoot configuration issue since I can run these projects in Eclipse and they run as expected. Could you help me with this problem? I can provided any needed information anytime.
