Solution

  • The version of Spring Cloud Kubernetes that you are using (1.1.10.RELEASE) requires Spring Boot 2.2.x. You are using 2.0.x. This older version of Spring Boot uses an older version of Spring Framework that does not contain the org.springframework.core.env.Profiles class. It was introduced in Spring Framework 5.1 and Spring Boot 2.0.x uses Spring Framework 5.0.x.

    You should update your dependency versions to ensure that they're compatible. To make it easier to do so, I would recommend using the spring-cloud-dependencies bom as shown on its project page.
