android - 用于SpringAndroid库的Android Proguard配置

Question

我的Android应用程序使用google-play-services_lib库和另一个库项目。反过来，此库项目使用很少的第三方库（SpringAndroid）来使用json格式的Web服务。

问题是，当我尝试导出应用程序时，proguard引发错误，并且过程停止。我的proguard配置如下。

    -verbose
    -dontskipnonpubliclibraryclassmembers
    -keepattributes *Annotation*,EnclosingMethod,Signature
    -keep class * extends java.util.ListResourceBundle {
        protected Object[][] getContents();
    }
    -keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable {
        public static final *** NULL;
    }
    -keepnames @com.google.android.gms.common.annotation.KeepName class *
    -keepclassmembernames class * {
        @com.google.android.gms.common.annotation.KeepName *;
    }
    -keepnames class * implements android.os.Parcelable {
        public static final ** CREATOR;
    }
    -keep public class com.mypackage.** {
      public void set*(***);
      public *** get();
    }
    -keep public class com.fasterxml.jackson.** { *; }
    -dontwarn com.google.code.rome.android.repackaged.** 
    -dontwarn com.fasterxml.jackson.databind.**
    -dontwarn org.simpleframework.xml.**
    -dontwarn org.apache.commons.**
    -keep public class org.springframework.http.converter.json.MappingJackson2HttpMessageConverter.** { *; }

由于某些原因，无法识别 -keep public class，现在我仍然低于 proguard错误。

           You should check if you need to specify additional program jars.
    there were 51 unresolved references to classes or interfaces.
              You may need to specify additional library jars (using '-libraryjars').
     java.io.IOException: Please correct the above warnings first.

 不知道我在想什么。如果为此配置 dontwarn，则 proguard剥离一些基本类。

通过将以下行添加到proguard-project.txt文件中，尝试消除警告：

-dontwarn org.springframework.http.client.**
-dontwarn org.springframework.http.converter.feed.**
-dontwarn org.springframework.http.converter.json.**
-dontwarn org.springframework.http.converter.xml.**
