如何解决收到的致命警报：pr otocol_version？我的java版本是1.7，maven版本是3.3.3

How to resolve the Received fatal alert: protocol_version ? My java version is 1.7 and maven version is 3.3.3

推荐答案

Sonatype 不再支持TLSv1.1及以下（生效日期为2018年6月18日） 。我的猜测是你正在使用TLSv1.1协议或以下。

Sonatype no longer supports TLSv1.1 and below (effective, June 18th, 2018). My guess is that you are using TLSv1.1 protocol or below.

我列出的文档为您提供了4个选项：

The documentation I listed gives you 4 options:

1. 升级Java运行时例如，使用OpenJDK构建或Oracle支持支持


2. 通过添加-Dhttps.protocols = TLSv1.2配置Java运行时以启用TLS 1.2


3. 使用支持TLS 1.2的Java版本的存储库管理器


4. 恢复为http，直到您可以执行上述修复步骤之一。

1. Upgrade your Java runtime, for example with OpenJDK builds or Oracle paying support
2. Configure your Java runtime to enable TLS 1.2 by adding -Dhttps.protocols=TLSv1.2
3. Use a repository manager that uses a Java version supporting TLS 1.2
4. Revert back to http until you can acheive one of the above remediation steps.

我自己通过使用-Dhttps.protocols = TLSv1.2作为VM参数来修复它。
 

I fixed it myself by just using -Dhttps.protocols=TLSv1.2 as a VM argument.
