I’ve never been more impressed by a Maven Plugin. Seriously, the Israfil Flex Maven Plugin is both well designed and well documented. take a look
It allows you to separate Flex projects into libraries (SWC) and applications (SWF). It integrates seamlessly with the technology-neutral features of Maven. Maven doesn’t care if you are working on Java or if you are working on Fortran. This is the first example I’ve seen of a technology other than Java working so well with Maven.
So, if you are looking for a way to seamlessly integrate Flex with Java. This plugin is for you. More fodder for my prediction that Maven’s second-coming is upon us.
