I'm creating some flash game using Adobe AIR. I try to compile it into .ipa file (to run on iPad device).
The project is not big, but not small also (it uses 6 swc libraries and lot's of not precompiled code). I try to package my game with Flash FDT 5.5 using both methods:
Packaging failed!

I know that this is common issue with Eclipse devlopment. I tried to solve that in standard way -> increase java heap size. As you can see I've set 3072M which should be sufficient.
When I try to compile smaller projects it works fine. I've got no idea what to do now :(. Any ideas?
After deep investigation I've found a solution. It was NOT due to any enviromnent configuration, but, as @Alan said, Adobe's packager was running into problems. As I suppose, it was meeting problems while 'optimalization' phase.
Here's a forum topic that was really usefull: http://forums.adobe.com/message/4445973#4445973
My project was using NAPE physic engine. As I found there: http://deltaluca.me.uk/forum/index.php/m/2148/0ce4c49cc2c79979154c56737d2978a4/ people meet problems with compilation time. In my case the compilation time was infinity ;), what ended with java's out of memory exception. The solution was to use newest NAPE build, which was a little bit optimalized by the author. This 'small optimalization' made my project working.
To sum up: if you have similiar problem, just check your code. Try to find some huge functions/methods, which Adobe's packager finds hard to optimalize.
