How to make ant build.xml for a working FlashBuilder project?
 

I have a Flex project that uses BlazeDS and I want to make an external build script so I can build the project outside of FlashBuilder. The eclipse environment lets you export an ant build xml file but it only has the java commands. Is there a way to export the mxmlc commands used by FlashBuilder to make an ant build file?

Finally got the syntax right. Here is the build file I ended up with:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!-- WARNING: Eclipse auto-generated file.
Any modifications will be overwritten.
To include a user specific buildfile here, simply create one in the same
directory with the processing instruction <?eclipse.ant.import?>
as the first entry and export the buildfile again. -->
