No qualifying bean of type 'org.springframework.security.oauth2.client.registration.ClientRegistrationRepository' available

When I try to build my project, I get this error message:

: Unsatisfied dependency expressed through method 'webClient' parameter 0; 
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: 
No qualifying bean of type 
'org.springframework.security.oauth2.client.registration.ReactiveClientRegistrationRepository' 
available: expected at least 1 bean which qualifies as autowire candidate.

this is my application.properties:

spring.security.oauth2.client.registration.eipo.authorization-grant-type=client_credentials
spring.security.oauth2.client.registration.eipo.token-uri=https://devapi.somedomain.co.xx/v1/auth/token
spring.security.oauth2.client.registration.eipo.client-id=randomClientId
spring.security.oauth2.client.registration.eipo.client-secret=T#%*sty%xp4^sdxb(e*
spring.main.web-application-type= reactive

this is my configclass:

@Configuration
public class WebClientConfig {
  @Bean
  WebClient webClient(ReactiveClientRegistrationRepository clientRegistrations) {
      ServerOAuth2AuthorizedClientExchangeFilterFunction oauth =
        new ServerOAuth2AuthorizedClientExchangeFilterFunction(
          clientRegistrations,
          new UnAuthenticatedServerOAuth2AuthorizedClientRepository());
      oauth.setDefaultClientRegistrationId("eipo"); 
      return WebClient.builder()
        .filter(oauth)
        .build();
  }
}

this is the service class:

@Slf4j
@Service
public class SettlementService
  @Autowired
  private WebClient webClient;

  public void getAuthThenGetResource(){
    ... //trying to get token
    log.info("got token");
    ... //get something from external resource
    log.info("got response");
  }
}

I've included the parent & dependency part of it. This pom.xml could be the cause, but I'm not sure. What's wrong with the webclient bean? I've tried many solution i found from stackoverflow, none have worked. Thank's for the help.

You have two items that need to be fixed.

Most importantly, with regards to missing beans is a missing 'starter'. In pom.xml replace

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-oauth2-client</artifactId>
    <version>5.3.13.RELEASE</version>
    <type>jar</type>
</dependency>

with

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-oauth2-client</artifactId>
</dependency>

When that is fixed it complains about a missing provider id. Adding the following to application.properties fixed that. You need to replace github with whatever provider is related to eipo:

spring.security.oauth2.client.registration.eipo.provider=github
