Multiple stubs in one file

I'm trying to group multiple stubs into one JSON file.

I've already ready read this post : Load wiremock stub files and this one https://github.com/tomakehurst/wiremock/issues/987https://github.com/tomakehurst/wiremock/issues/987

but I still can't make it work.

Currently, I have the following class:

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@AutoConfigureWireMock(port = 0, stubs = "classpath:/stubs/mappings", files = "classpath:/stubs")
public class ConfigurationTest {

@Autowired
  protected WireMockServer wireMockServer;

}

In my test/java/resources folder, I have :

mappings folder with different stubs

I'd like to have one file that contains all the stubs in the mappings.

I tried to create a .json file under mappings as below :

{
  "mappings" : [{
    
   ]}
}

but i get the following exception

Unrecognized field "mappings" (class com.github.tomakehurst.wiremock.stubbing.StubMapping), not marked as ignorable

If I try a json that starts an array, I also have an exception

Cannot deserialize instance of java.lang.String out of START_ARRAY token at

Do you have any idea on how to resolve this issue ? Thanks.
