Started stub server for project [] on port -1 - spring-cloud-contract

Question

I am trying to create a single (fat) spring boot jar for consumer with producer's stub as a dependency to it. With this, when i start-up the consumer app, it should start the contract stub as well.
Here is what I have done so far:
I used this pom example (https://github.com/spring-cloud-samples/spring-cloud-contract-samples/blob/master/producer_with_external_contracts/pom.xml#L98) and created a fat jar for producer
producer.pom
<plugin>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-contract-maven-plugin</artifactId>
<version>${spring-cloud-contract.version}</version>
<configuration>
<baseClassMappings>
<baseClassMapping>
<contractPackageRegex>.*contract.*</contractPackageRegex>
</baseClassMapping>
</baseClassMappings>
<contractDependency>
<groupId>com.groupId</groupId>
<artifactId>producer</artifactId>
</contractDependency>
<contractsMode>LOCAL</contractsMode>
<classifier>stubs</classifier>
<basePackageForTests>com.groupId.producer</basePackageForTests>
<convertToYaml>true</convertToYaml>
</configuration>
</plugin>
This is then imported into my consumer.pom like below:
<dependency>
<groupId>com.groupId</groupId>
<artifactId>producer</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
The application properties are as below:
producer - application.properties
server.port=8081
consumer - application.properties
stubrunner.ids=com.groupId:producer:+:stubs:8081
stubrunner.stubsMode=LOCAL
stubrunner.repositoryRoot=com.groupId.producer
stubrunner.minPort=8081
ControllerTests.java
#RunWith(SpringRunner.class)
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.MOCK)
#AutoConfigureMockMvc
#AutoConfigureJsonTesters
#AutoConfigureStubRunner( ids = "com.groupId:producer:+:stubs:8081",
stubsMode = StubRunnerProperties.StubsMode.LOCAL )
#DirtiesContext
public class ContractTests extends AbstractTest {
...
}
ConsumerApplication.java
#SpringBootApplication
#EnableWebMvc
#EnableStubRunnerServer
#Slf4j
public class ConsumerApplication {
...
}
ContractService.java
public class ContractService {
public #ResponseBody MockResponse verifyWithContract(SomeObj someObj) {
ResponseEntity<MockResponse> response = this.restTemplate.exchange(
RequestEntity
.post(URI.create( http://localhost:8081/someEndpoint ))
.contentType(MediaType.APPLICATION_JSON)
.body(someObj), MockResponse.class);
return response.getBody();
}
}
I have 2 issues:
When I run my test I get the below exception:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.cloud.contract.stubrunner.server.HttpStubsController': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'batchStubRunner' defined in org.springframework.cloud.contract.stubrunner.spring.StubRunnerConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.cloud.contract.stubrunner.BatchStubRunner]: Factory method 'batchStubRunner' threw exception; nested exception is java.lang.IllegalStateException: Remote repositories for stubs are not specified and work offline flag wasn't passed

at org.springframework.beans.factory.support.ConstructorResolver.autowireConstructor(ConstructorResolver.java:218) ~[spring-beans-5.1.5.RELEASE.jar:5.1.5.RELEASE]
I have also tried the below in test but that didn't help:
#AutoConfigureStubRunner( ids = "com.groupId:producer:+:stubs:8081",
stubsMode = StubRunnerProperties.StubsMode.REMOTE, rootRepository="com.groupId.producer" )
Ignoring the test failures, when i start the application, it starts fine with the below log lines

I think i am missing some stubRunner configuration for stubrunner port.
