MacOS java多版本安装与管理

Home - SDKMAN! the Software Development Kit Manager

# 安装sdkman

curl -s "https://get.sdkman.io" | bash

source "$HOME/.sdkman/bin/sdkman-init.sh"sdk version

正常出现sdkman版本号就安装成功了

# 安装java

# 安装java8

sdk install java 8.0.412.fx-zulu

建议和上述一样安装 fx-zulu 的jdk，这样会自带JAVAFX，方便后续使用java工具

ln -s ~/.sdkman/candidates/java/8.0.412.fx-zulu ~/.sdkman/candidates/java/8sdk use java 8java -version

# 安装jdk11

sdk install java 11.0.23.fx-zulu

ln -s ~/.sdkman/candidates/java/11.0.23.fx-zulu ~/.sdkman/candidates/java/11sdk use java 11java -version

# 安装jdk22

sdk install java 22.0.1.fx-zulu

ln -s ~/.sdkman/candidates/java/22.0.1.fx-zulu ~/.sdkman/candidates/java/22 sdk use java 22                                                            java -version

# 版本切换
