For many times I was facing issue when developers or QC could not figure out which application was deployed to test environment. There were attempts to guess checking functionality. Also this cause lot of misunderstanding inside of team. Here I will add version for Java web application build by Maven. So you could always check this version with specific URL.
Before describing solution for Maven I would like to mention very useful plugin for Grails in case you are using it. Build-info http://grails.org/plugin/build-info. This plugin will do everything you want end even more.
Few days ago I’ve received awesome present from DZone.com team for contribution. Not sure if there are anything that can motivates more to contribute and write. Presents are really nice but I would say the most valuable for me was such interest and acknowledgment. From the letter it is seen that currently there are 650K members and audience over 3 millions visitors. I am reading DZone for years and always was exited about quality of content, but now I am exited to be part of contributors team. With all my respect I want to say thank you to DZone team for creating, maintaining and making better such great resource.
