Spring errorCaused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'test'

Question

I'm getting this error during gradle build, spend whole day looking for solution but no luck. Using spring boot with gradle. I'm building simple test Rest api, basically when /test is called it will create an logging object and send that to another api ( seperate project and its running). Below are full error and my source files.

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'test': Unsatisfied dependency expressed through field 'testClient'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'my.com.cybersolution.skb.testproject.client.TestClient' available: expected at least 1 bean which qualifies as autowire candidate.

FeignClient needs to know where to locate the interfaces. Use this to do that -

@EnableFeignClients(basePackages = {"my.com.cybersolution.skb.testproject.client"})
