杰克逊和ProGuard的

Question

在我的Android应用程序，我遇到了一个例外：

java.lang.IllegalStateException: Conflicting property name definitions: 
    'keywords' (for [field com.myapp.d.q#a]) vs 'download_urls' 
    (for [method com.myapp.d.q#a(1 params)]) 

但是当我混淆我的代码，我没有当我运行在调试模式下的代码运行到这个异常。我在所以这里读了几回应并做了许多编辑proguard.cfg文件，这是它的外观：

-optimizationpasses 5 
-dontusemixedcaseclassnames 
-dontskipnonpubliclibraryclasses 
-dontskipnonpubliclibraryclassmembers 
-dontpreverify 
-verbose 
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/* 

-dontwarn org.w3c.dom.bootstrap.DOMImplementationRegistry 
-dontwarn android.text.* 
-dontwarn org.apache.commons.* 
-dontwarn org.scribe.services.* 
-dontwarn com.fasterxml.jackson.databind.** 

# Activities, services and broadcast receivers are specified in the manifest file so they won't be automatically included 
-keep public class * extends android.app.Activity

-keep public class * extends android.content.BroadcastReceiver

# Hold onto the mapping.text file, it can be used to unobfuscate stack traces in the developer console using the retrace tool 
-printmapping mapping.txt 

# Keep line numbers so they appear in the stack trace of the developer console 
-keepattributes SourceFile,LineNumberTable,*Annotation*,EnclosingMethod,Signature 

-keepclasseswithmembernames class * { 
    native <methods>; 
} 

-keepclasseswithmembers class * { 
    public <init>(android.content.Context, android.util.AttributeSet); 
} 

# Custom view components might be accessed from your layout files 
-keepclasseswithmembers class * { 
    public <init>(android.content.Context, android.util.AttributeSet, int); 
} 

# event handlers can be specified in the layout files e.g. android:onClick="nextButton_onClick" 
-keepclassmembers class * extends android.app.Activity { 
    public void *(android.view.View); 
} 

-keepclassmembers enum * { 
    public static **[] values(); 
    public static ** valueOf(java.lang.String); 
} 

-keep class * implements android.os.Parcelable { 
    public static final android.os.Parcelable$Creator *; 
} 

-keepclassmembers public class com.crittercism.* { 
    *; 
} 

-keepnames class com.fasterxml.jackson.** { 
    *; 
} 

但我不能让过去这个问题。我在这里做错了什么？我正在使用jackson 2.1.2 jars

Answer 1

修改proguard配置以包含“处理bean类”中提及的内容以及在POJO中指定jsonignoreproperties的组合确保了我可以通过错误并创建一个APK w/obfuscation。

Answer 2

首先，异常信息是obfscate，使用Retrace工具和Proguard来读取带有原始名称的消息。并再次发布异常消息。
