Install jEnv which will allow us to manage Java versions on global and local levels
brew install jenv
Now add jEnv to system PATH by updating configuration of macOS shell:
echo 'export PATH="$HOME/.jenv/bin:$PATH"' >> ~/.zshrc
echo 'eval "$(jenv init -)"' >> ~/.zshrc
Load updated terminal configuration:
source ~/.zshrc
Ensure proper integration with Maven:
jenv enable-plugin export
jenv enable-plugin maven
Install Java version(-s)
brew install java
Brew will install latest version of Java and add a symlink in /opt/homebrew/opt directory. For example, /opt/homebrew/opt/openjdk. There are other links inside of this directory which ultimately lead to the real folder where the installation is located:
/opt/homebrew/Cellar/openjdk/<javaversion>/libexec/openjdk.jdk/Contents/Home
So now we need to add all existing Java installations into jEnv by copying those paths and running the command jenv add <path>
jenv add /opt/homebrew/Cellar/openjdk/18.0.1/libexec/openjdk.jdk/Contents/Home
After that you can list available versions in jenv:
jenv versions
Here is how you can switch global and local Java versions.
Global version setup:
jenv global <version>
Directory (project) specific Java:
jenv local <version>
Java for current terminal window:
jenv shell <version>
And of course you can always check Java version in current context by
java -version
