PKIX path building failed: SunCertPathBuilderException: unable to find valid certification path to requested target
我这个报错主要是因为使用的maven库是https地址：
......
......
https://XXXXX
而这个url的证书在JDK的证书库不存在造成的
jre/lib/security/cacerts
因此，只需要将这个url的证书导出，再导入到cacerts中就可以了。
导入的方法可以使用命令，比如：
keytool -importcert -file jetty.crt -alias jetty -keystore $JAVA_HOME/jre/lib/security/cacerts
其它方法可参考如下文档：
"PKIX path building failed" and "unable to find valid certification path to requested target"
