注释类型 SerializedName 的属性“alternate”未定义

Question

I am using com.google.gson.annotations.SerializedName with elements "value" and "alternate" as mentioned in gson docs @SerializedName(value= "Active", alternate = {"Active","Pending"}) , but the compiler says error: "The attribute alternate is undefined for the annotation type SerializedName".

Answer 1

The alternate version of the @SerializedName annotation was added in Gson version 2.4, so will not work in earlier versions. It seems that occasionally the parent pom may prevent overriding the version (see above discussion).
