I occasionally receive reports about missing classes when building with ProGuard in Eclipse, in Windows. The cause is a mystery so far. ProGuard is run as a separate script/java process inside Eclipse. The problem happens spuriously.

You could try adding a pause or just list the files in the ProGuard script android-sdk/tools/proguard/bin/proguard.bat.
I have not received any similar reports about Ant or Gradle, so those may be practical alternatives.
