用于大查询的Proguard配置

Question

我使用以下gradle文件在我的项目中实现了大查询

   compile ('com.google.apis:google-api-services-bigquery:v2-rev328-1.22.0'){
    exclude module: 'httpclient' //by artifact name
    exclude group: 'org.apache.httpcomponents' //by group
    exclude group: 'org.apache.httpcomponents', module: 'httpclient' //by both name and group
}

在proguard文件中我添加了以下内容

-dontwarn com.google.api.client.**

 -keepclassmembers class * {
 @com.google.api.client.util.Key <fields>;
 }

-keepattributes Signature,RuntimeVisibleAnnotations,AnnotationDefault
 -dontwarn com.google.api.client.extensions.android.**
 -dontwarn com.google.api.client.googleapis.extensions.android.**

但我得到以下错误.

                Exception   = [java.lang.IllegalArgumentException] (Value "i" is not a        reference value [proguard.evaluation.value.UnknownIntegerValue])
                Warning:Exception while processing task java.io.IOException: java.lang.IllegalArgumentException: Value "i" is not a reference value [proguard.evaluation.value.UnknownIntegerValue]
                :app:transformClassesAndResourcesWithProguardForRelease FAILED
                Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.
                > java.io.IOException: java.lang.IllegalArgumentException: Value "i" is not a reference value [proguard.evaluation.value.UnknownIntegerValue]

我已经通过了可用的解决方案,但没有一个帮助.

任何帮助将不胜感激.谢谢.

将以下代码添加到proguard配置文件(proguard-project.txt)

-optimizations !class/unboxing/enum

这是Proguard的问题,问题讨论在这里
