I wanted to associate version and build information with every compilation of a Flex project. Such information is useful when deploying to different staging environments (e.g. are you sure you uploaded the correct SWF ?) and helps tracking feedback (e.g. bugs) from users using a particular build. First, I added a simple resource version.xml to store version and build info: <?xml version=‘1.0’ encoding=‘UTF-8’?> <version name=‘0.1’ build=‘124’/> Then I defined a component Version.
