1. 설치 가능한 JDK 검색

섹션 제목: “1. 설치 가능한 JDK 검색”
  • Homebrew 를 통해 설치가 가능한 JDK 를 검색
Terminal window
$ brew search jdk


  ==> Formulae
  openjdk          openjdk@11       openjdk@17       openjdk@8        jd               mdk              cdk

2-1) JDK 설치

섹션 제목: “2-1) JDK 설치”

  • 버전을 지정하여 설치할 경우

    Terminal window
      $ brew install openjdk@17

  • 버전을 지정하지 않고 가장 최신 버전을 설치할 경우

    Terminal window
      $ brew install openjdk

  • Command

    Terminal window
      $ brew install openjdk@17

      ==> Pouring openjdk@17--17.0.4.1.monterey.bottle.tar.gz
      ==> Caveats
      For the system Java wrappers to find this JDK, symlink it with
        sudo ln -sfn /usr/local/opt/openjdk@17/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-17.jdk
    

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

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

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

      ==> Summary
      🍺  /usr/local/Cellar/openjdk@17/17.0.4.1: 639 files, 305.5MB
      ==> 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`).

      $ sudo ln -sfn $(brew --prefix)/opt/openjdk@17/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-17.jdk

  • 버전을 지정하지 않고 가장 최신 버전을 설치할 경우

    Terminal window
      $ sudo ln -sfn $(brew --prefix)/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk

  • Command

3. JAVA_HOME 설정

섹션 제목: “3. JAVA_HOME 설정”

  • .zshrc 를 열어 아래의 설정값을 추가한다.

    • 버전을 지정하여 설치할 경우
      • JAVA_HOME=$(/usr/libexec/java_home -v17)
    • 버전을 지정하지 않고 가장 최신 버전을 설치할 경우
      • JAVA_HOME=$(/usr/libexec/java_home)

  • Commands

    • ① .zshrc 파일 열기

      Terminal window
        $ vim ~/.zshrc

    • ② .zshrc 파일 편집

      Terminal window
        === VIM START ===
        ...
        ### JAVA_HOME ###
        JAVA_HOME=$(/usr/libexec/java_home -v17)
      

        :wq
        === VIM END ===

    • ③ 변경 내용 적용

      Terminal window
        $ source ~/.zshrc

    • ④ 설정한 환경변수 내용 확인

      Terminal window
        $ echo $JAVA_HOME
