Eclipse Maven 错误：Received fatal alert: protocol_version -> [Help 1]

１.错误发生的场景：eclipse 项目运行 **maven install** ，报错了

２.错误的主要描述： Failed to execute goal org.apache.maven.plugins:maven-install-plugin:  
2.4:install (default-install) on project TENDJ:  
Execution default-install of goal org.apache.maven.plugins:maven-install-plugin:2.4:  
install failed: Plugin org.apache.maven.plugins:maven-install-plugin:  
2.4 or one of its dependencies could not be resolved:  
Failed to collect dependencies at org.apache.maven.plugins:maven-install-plugin:jar:2.4 ->  
org.codehaus.plexus:plexus-utils:jar:3.0.5: Failed to read artifact descriptor for org.codehaus.plexus:plexus-utils:jar:3.0.5:  
Could not transfer artifact org.codehaus.plexus:plexus-utils:pom:3.0.5 from/to central (https://repo.maven.apache.org/maven2):  
Received fatal alert: protocol\_version -> \[Help 1\]

３.根据翻译来说，主要是最后面这个问题，protocol\_version 也就是协议版本的错误，于是上网查找到了对应的原因　　　　maven Sonatype 中央仓库目前不再支持 TLSv1.1 以及以下的协议版本,通过chrome security 面板看到, 我自己使用的maven 中央仓库已经是 TLSv1.2 协议了

４.解决办法：

４.１.使用ｈｔｔｐ去访问ｍａｖｅｎ中央仓库（适用于对安全不严格的场景），修改ｓｅｔｔｉｎｇ．ｘｍｌ文件

<profiles>          
        <profile>  
            <id>maven-home</id>  
            <repositories>  
                <repository>  
                    <id>central</id>  
                    <url>https://repo1.maven.org/maven2</url>  
                    <releases>  
                        <enabled>true</enabled>  
                        <checksumPolicy>warn</checksumPolicy>  
                    </releases>  
                    <snapshots>  
                        <enabled>false</enabled>  
                    </snapshots>  
                </repository>  
            </repositories>  
      
        <pluginRepositories>  
            <pluginRepository>  
                <id>central</id>              
                <url>http://repo1.maven.org/maven2</url>              
                </pluginRepository>  
        </pluginRepositories>  
    </profile>

４.２.升级ｊｄｋ到１.８

４.３.通过添加 -Dhttps.protocols=TLSv1.2 , 配置 java runtime 参数,来 enable TLS 1.2

我用的就是第三种方法：

找到eclipse的jdk配置环境，在"Default VM arguments"这一栏填入：-Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2
