Execution failed for task ':transform ClassesWithJarMergingForRelease'解决办法

app在导入有赞商城之后，编译正常，但是在打包的过程中出现Execution failed for task ':transform ClassesWithJarMergingForRelease错误，冲突的包是okhttp网络请求框架

解决方案：

compile 'com.youzanyun.open.mobile:x5sdk:6.4.12',{
    exclude group:'com.android.support'
    exclude module: "okhttp"
}
