linux：Connect to repo.maven.apache.org:443 [repo.maven.apache.org/151.101.24.215] failed: 拒绝连接

报错如图所示

解决办法：

1、找到maven存放的目录

我这里是/opt/maven/

2、进入conf目录，对settings.xml文件进行编辑

将url替换成http://maven.aliyun.com/nexus/content/groups/public/

完整xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <mirrors>
    <mirror>
    <id>alimaven</id>
    <name>aliyun maven</name>
    <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
    <mirrorOf>central</mirrorOf>
</mirror>
    </mirrors>
</settings>

如此，便可解决问题
