Installation script

#!/bin/bash

# 校验参数
if [ ! "$1" ];then
  echo "请输入安装地址"
  return
fi

if [ ! "$2" ];then
  echo "请输入下载地址"
  return
fi

# 文件夹不存在则创建
if [ ! -d $1 ];then
  mkdir -p $1
  echo "======================= 创建文件夹 $1 ======================="
fi

# 下载maven安装包
if [ "$3" == "" ];then
  wget $2
else
  wget $2 -P $3
fi

# 下载maven安装包的名称
package_names=($(ls -t1 $3 | grep maven | grep tar.gz | awk '{print $1}'))
package_name=${package_names[0]}

# 解压安装包
if [ "$3" == "" ];then
  tar -zxvf $package_name -C $1
else
  unzip_path=$(cd $3 && pwd)
  tar -zxvf "$unzip_path/$package_name" -C $1
fi

# 获取解压后的文件夹名称
folder_names=($(ls -t1 $1 | grep maven | awk '{print $1}'))
folder_name=${folder_names[0]}

# 配置环境变量
install_path=$(cd $1/$folder_name && pwd)

echo -e "\n# maven配置" >> /etc/profile.d/my_env.sh
echo "export MAVEN_HOME=$install_path" >> /etc/profile.d/my_env.sh
echo "export PATH=\$MAVEN_HOME/bin:\$PATH" >> /etc/profile.d/my_env.sh
