'Is it possible to access a property value from another maven project?

I have a SpringBoot service:

package test;

@Service
public class TestService {

  @Value("${service.readTimeout}")
  private Duration readTimeout;
}

service.readTimeout is not declared in my current project's property files. It is linked in a separate project, which are all marked as Maven modules.

How is the value from the other property file being accessed by this project ?

The project is not listed as a dependency or mentioned in the pom.xml for the project that is using the value.

Does Maven connect all declared modules ? Are all files accessible from all projects ?

What is going on here ?

To get an external ressource you can use FileSystemResource, for example I have two projects demo and demo2 :

enter image description here

So I want to have access to demo application.properties from demo2,so you can use this code : 

Resource resource = new FileSystemResource("absolute path");
// for example : C:\\Users\\Developper\\eclipse workspace\\demo\\src\\main\\resources\\application.properties

Properties props = PropertiesLoaderUtils.loadProperties(resource);
System.out.println(props);

If you are forced to use annotations, you can try : @PropertySource("file:/path/to/propertiesfile") : https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/context/annotation/PropertySource.html
