在android中运行proguard时Jackson.jar中出错

我有一个android项目，它使用了

jackson-all-1.7.2.jar

使用此proguard.cfg文件运行proguard时：

-keep class com.actionbarsherlock.** {*;}
-keep class org.holoeverywhere.** {*;}

-libraryjars /libs/jackson-all-1.7.2.jar

我得到了一个例外：

注意，应用程序在没有proguard的情况下运行良好

当我在proguard.cfg中添加以下行时

-dontwarn org.codehaus.jackson

应用程序崩溃并报告此异常：

文件jackson-all-1.7.2.jar已经在您的libs目录中，因此Android Ant/Eclipse构建将自动获取该文件。你不应该用-libraryjars再次阅读它，因为这样你会得到关于重复的警告

Jackson正在使用反射来查找一些注释。ProGuard无法自动推断出这一点，它最终会删除相关的、似乎未使用的字段。此配置应使它们保持：

-keepclassmembers public final enum org.codehaus.jackson.annotate.JsonAutoDetect$Visibility {
    public static final org.codehaus.jackson.annotate.JsonAutoDetect$Visibility *;
}

---

将这些行添加到proguard配置文件中

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

---

您使用的是内置proguard还是其他版本？我使用的是与ADT捆绑的版本。谢谢，但我用Gson替换了Jackson
