App is failing with "required a bean of type 'brave.Tracer' that could not be found" while trying to get Sleuth's trace

Question

I am calling my Springboot app from another micro service to get the trace & span id's but getting error while starting the app. What I want to do is create Trace & Span in app1 and then call app2 and get the Trace id passed from app1 in app2. In app1 I am able to get the trace & span but in app2 where I want to fetch that trace its failing. I have tried to refer this.

Error that I get is:

Description:

Parameter 0 of constructor in com.test.demo1.filter.MyFilter required a bean of type 'brave.Tracer' that could not be found.

Action:

Consider defining a bean of type 'brave.Tracer' in your configuration." I also tried creating the bean but is giving error "The constructor Tracer() is undefined"

Below is my simple RestController & pom.xml

package com.test.demo1.controller;

import java.util.logging.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import brave.Tracer;


@RestController
@Component
public class Greeting {

private static final Logger logger = Logger.getLogger(Greeting.class.getName());
    
    @Autowired
    Tracer tracer;

    @RequestMapping("/greeting")
    public String greeting() {
        logger.info("Hello info from from spring sleuth");
        logger.info("tracer is -----> "+tracer.currentSpan().context().traceIdString());
        System.out.println("tracer-id :"+ tracer.currentSpan().context().traceIdString());
        return "Hello";
    }

}

You've provided Sleuth in version 1.0.0 which is a couple of years old. Please go to start.spring.io to generate a project with Sleuth as its dependency. Then you'll be sure that you don't have mixed up the dependencies manually.

Tried updating the sleuth version but same result. org.springframework.cloud spring-cloud-sleuth 2.1.3.RELEASE pom — vicky, Oct 08 '20 at 16:39
Please don't say any versions yourself. You're using boot 2.3 so you should be using sleuth 2.2. Please use the spring cloud bom as suggested in the documentation and by start.spring.io — Marcin Grzejszczak, Oct 08 '20 at 16:47
this got fixed if I changed the pom from spring-cloud-sleuth to spring-cloud-starter-sleuth . But do you know how did this relates to Bean not found error that Spring boot was throwing, could you please help me to understand. — vicky, Oct 08 '20 at 18:08

App is failing with "required a bean of type 'brave.Tracer' that could not be found" while trying to get Sleuth's trace
