Spring Not Initializing - App not starting

java.lang.IllegalArgumentException: Could not find class [org.springframework.cloud.netflix.feign.FeignAutoConfiguration]

Getting this error while running the Spring boot app. I have added the pom and the error log here. Tried changing from feign to openfeign but still won't work.

I have a dependency on sleuth for using 1.3.4.RELEASE version since I am trying to use SpanAccessor which has been deprecated after 2.0.0X

This is my pom

Solution

If you use spring-sleuth-version 1.3.2.RELEASE you should include this dependency:

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-feign</artifactId>
    </dependency>

However, this has no sense if you want to use openfeign (spring-cloud-starter-openfeign).

So... my advice is use spring-sleuth-version 2.x.x.RELEASE and follow https://github.com/spring-cloud/spring-cloud-sleuth/wiki/Spring-Cloud-Sleuth-2.0-Migration-Guide

It seems that the problem is spring-sleuth-version 1.3.2.RELEASE needs org.springframework.cloud.netflix.feign.FeignAutoConfiguration which is available in the dependency I've mentioned before.

Greetings.
