但是手工通过浏览器访问maven仓库一切正常

手工下载放到本地repository，然后再编译，这个错没了，又报下一个错，这么多包一个一个手工下载实在伤不起，

wtf，仔细一看，报错还有一句：Received fatal alert: protocol_version

原来是因为这个，官网地址：https://central.sonatype.org/articles/2018/May/04/discontinued-support-for-tlsv11-and-below/

这里粘贴一下answer：

If you are using http to access Central, or Java 8+ with https urls, you are not affected.

If you are on Java 7, it supports TLS 1.2 but it is disabled by default in versions before 1.7.0_131-b31, and the following Apache Maven workaround functions for older Java 7 users:

mvn -Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2 <goals>

or add the following to your environment or build script:

export MAVEN_OPTS=-Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2

If you are on Java 6, you will need to switch back to http or upgrade to a more modern Java version. Very recent versions of Java 6 claim to have TLS 1.2 support, but we have not confirmed it yet.

原来是因为maven*仓库不再支持TLSv1.1导致，jdk改为1.8问题解决。
