When I run "mvn dependency:tree", the result is as follows:
It shows that the maven-dependency-plugin version is 2.8.
I have checked the org.apache:apache:23 where the maven-dependency-plugin is managed and the its version is defined as 3.1.1. But the output of dependency:tree shows the version is 2.8. So I think it is not an updating issue but a bug.
