大神求助：使用NettyHttpClient 异步推送消息出错

Exception in thread "main" java.lang.NoSuchMethodError: io.netty.handler.ssl.SslContext.newClientContextInternal(Lio/netty/handler/ssl/SslProvider;[Ljava/security/cert/X509Certificate;Ljavax/net/ssl/TrustManagerFactory;[Ljava/security/cert/X509Certificate;Ljava/security/PrivateKey;Ljava/lang/String;Ljavax/net/ssl/KeyManagerFactory;Ljava/lang/Iterable;Lio/netty/handler/ssl/CipherSuiteFilter;Lio/netty/handler/ssl/ApplicationProtocolConfig;JJ)Lio/netty/handler/ssl/SslContext;

    at jgtest.Jpush.testSendPushWithCallback(Jpush.java:29)

以上为报错信息

pom.xml 里配置了全部jar包

在pom.xml里去掉原有项目springcloud包，则可以正常运行

```

org.springframework.cloud
spring-cloud-starter-ribbon
1.4.5.RELEASE
