1. homebrew 에서 Openjdk@17 다운로드 

$ java -version
    openjdk version "11.0.11" 2021-04-20

    ==> Caveats
    For the system Java wrappers to find this JDK, symlink it with
      sudo ln -sfn /opt/homebrew/opt/openjdk@17/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-17.jdk

    openjdk@17 is keg-only, which means it was not symlinked into /opt/homebrew,
    because this is an alternate version of another formula.

    If you need to have openjdk@17 first in your PATH, run:
      echo 'export PATH="/opt/homebrew/opt/openjdk@17/bin:$PATH"' >> ~/.zshrc

    For compilers to find openjdk@17 you may need to set:
      export CPPFLAGS="-I/opt/homebrew/opt/openjdk@17/include"

    ==> Summary
    🍺  /opt/homebrew/Cellar/openjdk@17/17.0.4: 640 files, 306.6MB
    ==> Running `brew cleanup openjdk@17`...
    Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP.
    Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).

 

2. jdk 버전 변경

# 링크 추가
$ sudo ln -sfn /opt/homebrew/opt/openjdk@17/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-17.jdk

# .zshrc에 추가
echo 'export PATH="/opt/homebrew/opt/openjdk@17/bin:$PATH"' >> ~/.zshrc

# 확인 및 코멘트 추가
$ vi ~/.zshrc
    ### MANAGED BY RANCHER DESKTOP START (DO NOT EDIT)
    export PATH="/Users/djkang/.rd/bin:$PATH"
    ### MANAGED BY RANCHER DESKTOP END (DO NOT EDIT)

    # openjdk17 
    export PATH="/opt/homebrew/opt/openjdk@17/bin:$PATH"

# zshrc 변경사항 적용
$ source ~/.zshrc

 

3. jdk 변경 확인

# 위치 확인
$ which java                                    
    /opt/homebrew/opt/openjdk@17/bin/java

# 버전 확인
$ java -version
    openjdk version "17.0.4" 2022-07-19
    OpenJDK Runtime Environment Homebrew (build 17.0.4+0)
    OpenJDK 64-Bit Server VM Homebrew (build 17.0.4+0, mixed mode, sharing)
