Subject Re: Computing the maven dependency graph at runtime for unit tests?
Date Tue, 07 Apr 2015 06:41:32 GMT is how we deal with this.
At he beginning of each release cycle we review the versions of the 
third party libraries that we use and update the dependencies in our 
aggregation projects.

Our application modules depend on the current version of the aggregation 
projects so developers can not change the version of a third-party 
library without changing an aggregation project which they are not 
allowed to do without the project manager's approval.
If a new library has to be added to support a new feature, this requires 
a review by the project team.

This makes everyone's life a lot simpler.
Our application projects only have a few dependencies even if we use 
dozens of Apache product as well as a few from other providers.

This also makes testing and QA a lot easier since if something stops 
working, you can be sure that it is not a third-party library getting 
changed by another developer.

We have not had to automate the enforcement of this policy.
However, we do have an SCM with history and I would know who to beat on 
if someone did an unauthorized upgrade.
