Maven二进制安装

tips::: 其中用到了sed多行插入的命令，可以参考 :::

#!/bin/bash

install(){
url="https://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz"
filename=`basename $url`
[ -f $filename ] || wget $url

tar xf $filename -C /usr/local

ln -s /usr/local/${filename%-bin.tar.gz} /usr/local/maven

echo 'PATH=/usr/local/maven/bin:$PATH' > /etc/profile.d/maven.sh

cat > /etc/profile.d/maven.sh <<-EOF
PATH=/usr/local/maven/bin:$PATH
export MAVEN_HOME=/usr/local/maven
EOF

. /etc/profile.d/maven.sh

mvn -v && echo 安装成功，请重启shell || echo 安装失败
}
