I had same exception while starting springCloudConfigServer project.

Root cause was incorrect value for the below property in application.properties (Typo mistake)

Before: management.endpoints.web.exposure.include=bus=refresh

I changed it like below and my project started successfully management.endpoints.web.exposure.include=bus-refresh

After some investigation time, it appears that I should use a different version of Spring Cloud.

I changed from Finchley.M8 to Finchley.SR2 and everything starts working fine.

Spring Cloud + Spring Boot 2.0.x compatibility notes: https://github.com/spring-projects/spring-cloud/wiki/spring-cloud-finchley-release-notes
