how do I compile Flash .FLAs using command line?
I am using Eclipse + FDT for Flash development and I would like to use ANT to automatize the compilation.
I am using AS3 and need to compile for Flash Player 10.1.
Many thanks
Update: I need to compile .FLAs because that's what I get from our designers.
To sum up what might not be apparent in the other answers: FLA files are not exactly "source", but more like project files for the Flash authoring tool, and the only thing that knows how to compile them is that tool. If you have Flash Professional and it's open, it's possible for other tools (or the command line) to tell it to compile, but that's the best you can do unless you change your workflow somehow - such as by getting something other than FLAs from your designers, or by you giving scripts, SWCs, etc. to the designers for them to import and compile.
With that said, in the most recent version Adobe has changed FLA files from what they used to be (a gory binary memory dump of the authoring tool) into a much more accessible zipped folder full of XML and images and so forth, so in the future it should become feasible for 3rd party tools to do something useful with FLAs. But at the moment, the format of said XML is apparently not stable yet, and I haven't heard of any other tools starting to process FLAs yet.
