[logback-user] Android pro guard warnings building with ant

[Chris Kelly]

Hello,

I've been building an app with log back-android and have it configured to use file and logcat appenders. It works exactly as I want when building a debug version via Eclipse ADT or with 'ant debug'. However, with a release build and Proguard enabled, I have ~50 warnings locating referenced classes from the  javax.xml.Stream package. As far as I can tell, this package doesn't existin in android. Is there any additional dependency I have overlooked?

I have downloaded both the slf4j and logback-android jar's and added the documented Proguard rules to my project as well.

Below is a sample of my 'ant release' build log where project1 is my app and dependency is an android library project.
