Release version in build?

Every time, I build the project, the generated WAR version is increased... I'm now at xwiki-0.9.11.war!! I think there's something wrong with the build. I've also noticed something wrong which may be related: The build generates a version.properties file in the src/ tree. This is wrong: all generated files should go in target/ and not in the src tree. In addition this file is no in the ignore file which means that someone may have added it to the SCM and I may have committed changes to it in my directory refactorings. Thanks -Vincent
