关键词：jdk17 jdk11 jdk8 MAC

最近基本都要求使用jdk17 jdk11 用jdk8的也逐渐在升级

那么开发机就要安装多套jdk

在已经安装8的基础上安装17

配置示例

# 配置jdk路径
export JAVA_8_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_192.jdk/Contents/Home
export JAVA_17_HOME=/Library/Java/JavaVirtualMachines/jdk-17.0.2.jdk/Contents/Home
 
# 设置默认jdk版本
export JAVA_HOME=$JAVA_8_HOME
 
# 配置alias命令动态切换jdk版本
alias jdk8="export JAVA_HOME=$JAVA_8_HOME"
alias jdk17="export JAVA_HOME=$JAVA_17_HOME"

继续安装11
