How to inject SVN revision number into JAR?

I want my JAR/WAR application to know what is the SVN revision number of its sou开发者_如何学JAVArce code. I want this revision number to be later rendered for web end-users at the bottom of a web page, etc.

Is there any existing Maven plugin to automate the process? I think that the plugin has to collect the information from svn and save to some file, like src/resources/revision.txt.

This page provides the answer to an almost identical problem:

Maven CookBook: How To Add SVN Revision To A JAR Manifest?

In your case, instead of building a manifest entry, you need to use the buildNumber variable for resource filtering

use the versions-maven-plugin buildnumber-maven-plugin from the Codehaus Mojo project. Provides lots of options to do this.

You can use svn keyword substitution
