Proguard: AmazonAWS und MBean Ausgabe

Question

Ich versuche ein Scala-Projekt mit Proguard zu verkleinern, das die Amazon AWS-Bibliotheken benötigt. Die ursprüngliche JAR-Datei funktioniert wie erwartet, aber die geschrumpfte gibt die Ausnahme aus, dass einige Klassen keine MBean-Konventionen implementieren. Ich habe einige ähnliche Probleme aussortiert, bevor ich "-keep" -Optionen verwendete, aber dieses Mal bin ich verloren.

Irgendwelche Ideen, wie man es löst, werden geschätzt?

Answer 1

Sie müssen ProGuard anweisen, die MBean Klassen nicht-verschleierten zu halten die Standard-MBean Konvention zu folgen. Regeln, wie dies ausreichend sein:

-keep class **MBean { 
    void set*(***); 
    void set*(int, ***); 

    boolean is*(); 
    boolean is*(int); 

    *** get*(); 
    *** get*(int); 
} 

Diese ProGuard anweisen alle Klassen zu halten, die Namen wie * MBean haben und halten auch keine Getter/Setter.
