eClipse Photon- Run As: maven install hit "Error: Could not find or load main class TLSv1.2"

Caused by: javax.net.ssl.SSLException: Received fatal alert: protocol_version



JDK 7 issues from https://feitianbenyue.iteye.com/blog/2429045:

由于我的同事, 使用的 jdk 是 1.7 , jdk1.7虽然支持TLS 1.2 但是默认是 disabled的, 所以就会出现上面的 Received fatal alert: protocol_version  异常

下表格是 根据Oracle文档 各版本JDK默认使用的TLS协议：

	JDK 8 (March 2014 to present)	JDK 7 (July 2011 to present)	JDK 6 (2006 to end of 2013)
TLS Protocols	TLSv1.2 (default) TLSv1.1 TLSv1 SSLv3	TLSv1.2 TLSv1.1 TLSv1 (default) SSLv3	TLS v1.1 (JDK 6 update 111+) TLSv1 (default) SSLv3
