Problema con Android Proguard: sigue recibiendo el error "java.io.IOException: no se puede procesar la clase..." cuando se omite la ofuscación

Question

Estoy creando una aplicación de Android con programa en Android Studio y mi proyecto tiene una biblioteca (na.jar) que me gustaría omitir la ofuscación y la verificación previa porque algunas clases de na.jar me están dando errores durante la compilación. Así que en mi archivo de configuración de programa, tengo las siguientes opciones

-dontpreverify
# com.na, org.json are packages in na.jar, don''t obfuscate the code in these packages
-keep class com.na.** { *; }
-keep interface com.na.** { *; }
-keep class org.json.** { *; }
-keep interface org.json.** { *; } 

Sin embargo, todavía estoy recibiendo los siguientes errores relacionados con las clases defectuosas en na.jar durante el proceso de compilación.

Caused by: java.io.IOException: Can''t read [C:/StudioProjects/PBActivity/pBActivity/libs/na.jar(;;;;;;!META-INF/MANIFEST.MF)] (Can''t process class [com/na/util/BinConverter.class] (256))

Entonces, ¿proguard sigue leyendo las clases y los frascos incluso con la ofuscación omitida? Soy nuevo en el uso de proguard para construir aplicaciones de Android.

También tengo problemas con pro guard pero me resultó más útil seguir el código de git hub.

Build.grade

buildscript {

prueba esto:

-dontwarn com.na.**
-keep class com.na.** { *; }
-keepattributes Signature
-keepattributes Exceptions
