   重点在于 : javax.net.ssl.SSLException: Received fatal alert: protocol_version , ssl 协议版本存在问题。
   在 github 的 Weak cryptographic standards removal notice 中有提到，取消 TLSv1/TLSv1.1 的连接方式，对于jdk1.7 的用户可以显示的进行配置，对于jdk1.6 的客户建议升级jdk版本，jdk1.8及以上版本支出 TLSV1.2，故不用配置。

3. 解决方法
   我本地是1.7 需要进行相关的配置操作。
   操作： 在 eclipse.ini 文件的最后加上 -Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2（另起一行）
