Description:

An attempt was made to call the method com.google.gson.GsonBuilder.setLenient()Lcom/google/gson/GsonBuilder; but it does 

not exist. Its class, com.google.gson.GsonBuilder, is available from the following locations:

    jar:file:/G:/lib/gson-2.3.1.jar!/com/google/gson/GsonBuilder.class

It was loaded from the following location:

    file:/G:/lib/gson-2.3.1.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of 

com.google.gson.GsonBuilder

提升了版本2.7，2.8.2，但是均没有解决版本冲突的问题，最后发现，是我之前手动添加过gson.jar。删除即可。比较常规，但是由于用maven管理jar包，在pom.xml中找不到冲突的jar所以在这里记录一下，提个醒。下面是先删除本地jar之后的现象，再删除这些就可以了
