java 설치

 

만약 homebrew 설치가 되어 있지 않다면, 아래 글을 참고하여 설치한다.

homebrew path 설정

 

다음은 brew로 java를 설치하는 방법이다.

 

1. 터미널을 오픈하여 openjdk를 설치한다.

lazy@MacBook-M1-Pro % brew install openjdk
...
If you need to have openjdk first in your PATH, run:
  echo 'export PATH="/opt/homebrew/opt/openjdk/bin:$PATH"' >> ~/.zshrc

For compilers to find openjdk you may need to set:
  export CPPFLAGS="-I/opt/homebrew/opt/openjdk/include"
==> Summary
🍺  /opt/homebrew/Cellar/openjdk/23.0.2: 602 files, 337.8MB
==> Running `brew cleanup openjdk`...
Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP.
Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).

 

2. 환경변수에 java 설치 위치를 path 설정한다.

lazy@MacBook-M1-Pro % echo 'export PATH="/opt/homebrew/opt/openjdk/bin:$PATH"' >> ~/.zshrc
lazy@MacBook-M1-Pro % source ~/.zshrc

 

3. java 버전을 확인한다.

lazy@MacBook-M1-Pro % java -version
openjdk version "23.0.2" 2025-01-21
OpenJDK Runtime Environment Homebrew (build 23.0.2)
OpenJDK 64-Bit Server VM Homebrew (build 23.0.2, mixed mode, sharing)
