接入阿里sdk报java.lang.NoSuchMethodError: com.google.gson.JsonObject.keySet()Ljava/util/Set；
项目中完成短信发送验证码,用到某平台的SDK接口,结果启动模块时报错,抛出 java.lang.NoSuchMethodError: com.google.gson.JsonParser.parseString(Ljava/lang/String;)Lcom/google/gson/sonElement; 异常.
开始感觉也没多大毛病.可能就是用它SDK本身用的某个jar包升级了,已经不用或没有这个方法. 第一想到的就是找下项目中 jar 版本入手.
找到是GosnJa

在项目依赖比较复杂或者 Java 运行的环境有问题时，或者同一类型的 jar 包有不同版本存在，都可能触发该错误。本质上说是 JVM 找不到某个类的特定方法，也就是说 JVM 加载了错误版本的类。说白了，就是 JVM 找不到真正想要调用的方法啦！出现该错误的情形主要有以下两个种： 
导入了不匹配的包版本；开发环境和运行环境不一致。 
2 解决方法 
查看“External Libraries”，看报错的方法到底存不存在，如果不存在，说明这个包一定有问题啦，更新包就可以啦；如果存在，说明包已...
