From time to time it is good to see what are the latest versions of the libraries you use (because maybe you would like to upgrade). With Maven you can use the Versions Maven Plugin, but you will get better results if you add a simple bash script. Let me show you how.

Sooner or later your CI server will became very busy, and your frustration will grow because of increasing wait time for each build. One thing you can do to improve the situation is to avoid running jobs when there is no need to do so.

I use Jenkins + Maven + SVN in this example, but you can use this "tricks" also when using different technologies - Gradle, Git etc.
