外部jar库的java Proguard问题

Question

我正试图在我的安卓应用程序中使用Unirest，遵循本教程：http://blog.mashape.com/using-unirest-java-for-your-安卓-projects/

在新的空项目中，我导入了external*jar，正如在guide中一样，我遇到了以下错误：

Error:warning: Ignoring InnerClasses attribute for an anonymous inner class

我发现这是由Proguard引起的。我已经尝试过以下解决方案：

这是我的身材。格拉德尔：

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-安卓.txt'), 'proguard-rules.pro'
    }
}

proguard规则。pro-项目中

-keepattributes EnclosingMethod
-keepattributes InnerClasses
-dontoptimize
-optimizations optimization_filter
-dontwarn InnerClasses

和proguard androd。在/Library/Android/sdk/tools/

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-verbose 
-keepattributes EnclosingMethod
-keepattributes InnerClasses
-dontoptimize
-optimizations optimization_filter 

谢谢你的帮助
