External auto configured feign client not autowiring

I am creating an external jar to add as a dependency to multiple spring boot projects.
I am trying to make it auto configure itself to find and autowire a feign client.
When the application attempts to start it fails with:

FeignConfiguration required a bean of type ‘org.springframework.cloud.openfeign.FeignClientFactory’ that could not be found.

External project pom.xml:

        </dependency>
        
    </dependencies>
</project>

External project Feign Client:

@FeignClient("java-app-c")
public interface MyFeignClient {
    @GetMapping("/")
    public String get(@RequestParam(name = "name") String name);

External project Feign Configuration Class:

@Configuration
@EnableFeignClients(clients = MyFeignClient.class)
public class FeignConfiguration {
    @Autowired
    private MyFeignClient feignClient;
}

External project spring.factories file (src/main/resources/META-INF/spring.factories

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.abc.FeignConfiguration

For the EnableFeignClients annotation I have also tried using the base package of ‘com.abc’ but it doesn’t change the result

  • Does your application, which uses external jar, have spring-cloud-starter-openfeign included as dependecy?
