In June 2018, in an effort to raise security and comply with modern standards, the insecure TLS 1.0 &amp; 1.1 protocols will no longer be supported for SSL connections to Central. This should only affect users of Java 6 (and Java 7) that are also using https to access central, which by our metrics is less than .2% of users.

The following command helped me (executing on bash before running mvn)

<pre><code>export MAVEN_OPTS=-Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2

blocks|key|4188164|text|对不起，我不知道你为什么会收到这个错误信息。但是，我使用的是Java7和Windows10，我的解决方案是通过更改JAVA_HOME环境变量暂时使用Java8。然后，我可以运行mvn+install并从Maven+Central+Repository获取数据。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4188165|entityMap^0|1L|9|2G|B|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

I'm sorry, I don't know why you get the error message. However, I'm using Java 7 and Windows 10 and the solution for me was to temporarily use Java 8 by changing the <code>JAVA_HOME</code> environment variable. Then I could run <code>mvn install</code> and fetch from Maven Central Repository.

Update maven version to 3.6.3 and run

I'm getting the below errors when connecting to Maven Central / <a href="https://repo1.maven.org" rel="noreferrer">https://repo1.maven.org</a> after June 18th 2018.

<pre><code>Received fatal alert: protocol_version
</code></pre>

or

<pre><code>Received fatal alert: peer not authenticated

Why am I getting "Received fatal alert: protocol_version" or "peer not authenticated" from Maven Central?

在2018年6月18日之后连接到Maven Central / 时，我得到了以下错误。Received fatal alert: protocol_version或Received fatal alert: peer not authenticated

问为什么我会收到来自Maven Central的“接收到致命警报: protocol_version”或“同级未经过身份验证”？
