Spring is getting properties from different module. Why?

Question

My maven project has three modules:

Dummy-project
  - Module A
    - Module A1
    - Module A2
      - src/main
        - java
          - HttpMetaDataUtil.java
        - resources
          - config/beta
            - application.properties
  - Module B
    - src/main
        - resources
          - config/beta
            - application.properties
  - Module C

In module A2, using file HttpMetaDataUtil.java, I want to read contents from properties file (residing inside module A2 only).

HttpMetaDataUtil.java

@Getter
@Setter
@Component
@PropertySource("classpath:config/beta/application.properties")
@ConfigurationProperties(prefix = "api.verification")
public class HttpMetaDataUtil {

    private Map<String, String> smartCard;


}

Module A2/src/main/resources/config/beta/application.properties

# SmartCard related properties
api.verification.smartCard.path=https:dummy_data
api.verification.smartCard.retryDelay=1000
api.verification.smartCard.serviceTimeout=30000

But smartCard map is getting set as null.

When I put the above properties config in Module B/src/main/resources/config/common/application.properties, it is taking the properties from this file.

Module B/src/main/resources/config/beta/application.properties

# SmartCard related properties
api.verification.smartCard.path=https:dummy_data
api.verification.smartCard.retryDelay=1000
api.verification.smartCard.serviceTimeout=30000

This means that HttpMetaDataUtil.java (residing under module A2) has classpath set for Module B.

I verified it by changing the @PropertySource line in HttpMetaDataUtil.java to @PropertySource("classpath:config/beta/application_new.properties") and creating application_new.properties file only in module A2, and it is throwing fileNotFound exception.

java.io.FileNotFoundException: class path resource [config/beta/application_new.properties] cannot be opened because it does not exist

When I created application_new.properties file also in module B, it is picking properties from this file.

Can anyone please tell why Module A2 class is picking properties from Module B? Is something I am missing related to classpath?

I did. It is throwing the same error. One thing to note is my main application file is located in module B. — AB Hi Shek, Mar 11 '20 at 06:51

@M.Deinum No. Actually module A1 and A2 are dependencies of module B. — AB Hi Shek, Mar 11 '20 at 08:44
Which explains it. The name and location are the same (root of classpath) and it will only read a single file from that location. The one in Module B has a higher precedence. Either use a single file for all or change the names. — M. Deinum, Mar 11 '20 at 09:19
