Estou com um problema no Proguard e no uso de bibliotecas externas. Meu projeto é compilado sem erros e executado com êxito em um dispositivo real, mas somente quando eu o executo no Eclipse. Agora eu quero fazer uma versão ofuscada, então fiz o seguinte: executei "android update project -p ./"

proguard.dir=/home/stoned/android-sdk-linux_86/proguard4.5.1/lib
proguard.config=/home/stoned/workspace/Fidoo/proguard.cfg

quando executo o "ant release", recebo o seguinte:

... skipped many irrelevant messages ...

Obviamente, javax.swing. As classes não são necessárias no aplicativo Android, bem como as classes log4j. Como faço para proguard não procurar por essas bibliotecas referenciadas?
