Oauth2+jwt非依赖冲突报NoSuchMethodError如何定位问题

问题遇到的现象和发生背景

做一个demo尝试SpringCloudAlibaba+Oauth2+jwt进行统一认证，获取token正常，在get请求header携带token进行gateway认证时，报class NoSuchMethodError。关键依赖版本如下：

springcloud：Hoxton.SR12
SpringCloudAlibaba：2.2.6.RELEASE
Security和Oauth相关：5.3.9

运行结果及报错内容

java.lang.NoSuchMethodError: com.nimbusds.jose.Header.toJSONObject()Lnet/minidev/json/JSONObject;
