Android: Problems building apk with Ant Release

I have no problems building my app in eclipse but once I try to do it via ant, it does not build. I've used "android update project -p ." to generate the build build.xml and proguard.cfg file. I tried "ant compile" and it builds fine as well. The app includes a android library and has external libs if it matters. Anyone here's the error that prints out when I try to do a "ant release",

UNEXPECTED TOP-LEVEL EXCEPTION:

I'm pretty much perplexed at the moment so hopefully someone can shed some light.

I think my answer on this page also applies on this error. This happens when you initialize an anonymous class in dead code.

An explanation why it would only happen in release and not in debug is that the dead code is removed when optimized.

Read carefully this page:

http://developer.android.com/tools/projects/projects-cmdline.html

You can try one of these solution:

1) One-line command

android update project -p --subprojects

2) Update the build.xml file of both the main project and the library project:

android update lib-project --path myPath/Lib    
android update project --name android_app --path . --library myPath/Lib

After 1) or 2)

ant clean
ant release
