mac下安装多个jdk ¶

官网：https://www.oracle.com/java/

官网下载： https://www.oracle.com/java/technologies/downloads/ MAC下载： https://www.oracle.com/java/technologies/downloads/#jdk17-mac 镜像源： https://mirrors.tuna.tsinghua.edu.cn/Adoptium/17/jdk/

1、打开官网 https://www.oracle.com/cn/java/technologies/downloads/ 选择17，macos。A

ARM64 DMG Installer：现在新款mac使用，Apple芯片 x64 DMG Installer：老款mac使用，inter芯片

起因是macOS下安装Oracle官方的JDK10后，kettle启动报错，需要切至JDK8。

安装 ¶

双击安装

添加环境变量、添加切换脚本 ¶

执行 vim ~/.bash_profile，然后加入如下内容：或者执行 open -t ~/.bash_profile 配置


# ===== Switch JDK =====
export JAVA_HOME_JDK8  = "/Library/Java/JavaVirtualMachines/jdk1.8.0_192.jdk/Contents/Home"
