There are some closed issues about guava, but problem is still here. spring-cloud-starter-netflix-ribbon uses guava transitive dependencies of different versions. Therefore maven-enforcer-plugin fails for my projects. Please consider to use maven-enforcer-plugin in netflix projects to make dependencies convergence up to date. Or update guava dependencies to one version or consider not to use guava.
There is guava transitive dependencies graph:
You can see guava versions: - 16.0 - 16.0.1 - 19.0 for Spring Cloud Netflix 2.1.4
