About
There are a few ways to get a timestamp in your maven build. Unfortunately most of them make you jump through giant hoops. This maven plugin makes it as simple as 1-2-3 to create a timestamp at your disposal.
Also, it enables you to use the syntax of SimpleDateFormat to form custom formatted dates.
This plugin is maintained for legacy reasons only. The current versions of maven have a property called maven.build.timestamp that has the exact feature set of this plugin. See http://maven.apache.org/guides/introduction/introduction-to-the-pom.html
As of Jan 2012 the maven-timestamp-plugin is available in the central repository.
