Automated Nightly Build using Flash Builder Standard

I have a license of Flash Builder 4.6 Standard on Windows. I can build my project manually using Export Release Build.

I'm trying to setup an automated nightly build. All the examples I found use the fb.exportReleaseBuild ant task in the xml file. But this feature requires a license of Flash Builder Premium.

Is there any other method available that I can use with the Standard license? Any other ant tasks or functions available to build using command line?

thanks
