mvn 下载地址：https://maven.apache.org/download.cgi

选择一个合适的版本

cd /opt && curl -o apache-maven-3.8.6-bin.tar.gz https://dlcdn.apache.org/maven/maven-3/3.8.6/binaries/apache-maven-3.8.6-bin.tar.gz
tar -xzf apache-maven-3.8.6-bin.tar.gz
sudo echo 'export PATH=\$PATH:/opt/apache-maven-3.8.6/bin:$PATH' >> /etc/profile
suco source /etc/profile

配置镜像仓库：

cd /opt/apache-maven-3.8.6/conf
vi settings.xml

找到 mirrors 的标签，注意不要添加到注释里面，多个镜像，mvn 只会选择使用 第一个

    <mirror><id>repo1.maven.org</id><name>repo1 maven</name><url>https://repo1.maven.org/maven2/</url><mirrorOf>central</mirrorOf></mirror><mirror><id>dist.wso2.org</id><url>https://dist.wso2.org/maven2/</url><name>repo apache</name><mirrorOf>dist</mirrorOf></mirror><mirror><id>repo.maven.apache.org</id><url>https://repo.maven.apache.org/maven2/</url><name>repo apache</name><mirrorOf>repo</mirrorOf></mirror>
