I also had a dependency conflict issue.

I was using this dependency. maven-project-info-reports-plugin 3.8.0 This includes guava-10.0.1.jar.

You can find out by clicking on the Dependency Hierarchy tab at the bottom of your pom.xml if you are using eclipse, and searching for guava.

Changing the maven-project-info-reports-plugin version solved the problem.

In my case, strangely enough, this conflict sometimes occurs and sometimes does not occur depending on the environment.

It seems like it would be good to always monitor for dependency conflicts.
