Запутывание ActionBarSherlock с помощью Proguard

Я пытаюсь запутать свое приложение для Android, используя proguard и ant ( eclipse+ proguardникогда не работает, всегда выдает ошибку 1). Но я получаю файл класса ... неожиданно содержит класс ... предупреждает всех об этом месте, и сборка завершается неудачно. Я также пробовал с опцией -ignorewarningsв proguard. Сборка прошла успешно, но я получил непригодный для использования пакет.

Вот вывод ant:
