proguard hell - can't find referenced class

So, I'm TRYING to release some software but Proguard is giving me a headache.

When I try to export using proguard I'm getting lots of warning ie "can't find referenced class"

For example: 

[2011-08-07 17:44:37 - GAME] Warning: org.simpleframework.xml.stream.StreamReader: can't find referenced class javax.xml.stream.events.XMLEvent
[2011-08-07 17:44:37 - GAME] Warning: there were 52 unresolved references to classes or interfaces.
[2011-08-07 17:44:37 - GAME]          You may need to specify additional library jars (using '-libraryjars'),
[2011-08-07 17:44:37 - GAME]          or perhaps the '-dontskipnonpubliclibraryclasses' option.
[2011-08-07 17:44:37 - GAME] java.io.IOException: Please correct the above warnings first.
[

The warnings seem to related to simpleframework, so in my proguard config file I've added the following:

-libraryjars pathtoprojecttolibs\simple-xml-2.4.jar

Where pathtoprojecttolibs is the path to jars which are referenced by my project.

This makes NO difference.

If simpleframework references javax can I tell proguard to ignore this too??

Any ideas?

This error occurs because the libs you use depend on other libs which are not realy used, but Proguard is looking for them.
Add your -dontwarn lines to your proguard-rules.pro file in your Android project to disable this warnings.

You can find which dependencies you need to add to your proguard-rules.pro in the stacktrace of your error.

In my case I haven't changed anything and warning started to show. The problem was with broken gradle caches. Check my other answer. I share with this because it took my 2 hours to find the problem :]

Add this line to your proguard-rules.pro file in the gradle scripts directory:

-dontwarn package.class.name.**

where package.class.name is the package name with the class name of the jar file appended.

For example:

-dontwarn com.myexternalclass.utils.**
