Prerequisites

Libraries

Troubleshooting

Ensure Java Home variable is set

echo $JAVA_HOME

Should see

/Library/Java/JavaVirtualMachines/jdk-17.0.1.jdk/Contents/Home

If not, you either don't have it downloaded, or Java Home variable is not set.

Ensure Java version is downloaded

/usr/libexec/java_home -V

Should see installed JDKs:

17.0.1 (x86_64) "Oracle Corporation" - "Java SE 17.0.1" /Library/Java/JavaVirtualMachines/jdk-17.0.1.jdk/Contents/Home
16.0.1 (x86_64) "Oracle Corporation" - "OpenJDK 16.0.1" /Users/user/Library/Java/JavaVirtualMachines/openjdk-16.0.1/Contents/Home
11.0.13 (x86_64) "Oracle Corporation" - "Java SE 11.0.13" /Library/Java/JavaVirtualMachines/jdk-11.0.13.jdk/Contents/Home
...

If not found, have not downloaded the JDK properly.

Ensure correct v17 is showing

/usr/libexec/java_home -v 17

Should see

/Library/Java/JavaVirtualMachines/jdk-17.0.1.jdk/Contents/Home

If you see a non-Oracle JDK, like open JDK, you need to uninstall it first.

Set Java Home variable

Find out what shell version you're using:

echo $SHELL

If you're using ZSH: you ought to be updating ~/.zshrc else ~/.bash_profile for the following steps.

Update your profile:

[emacs/vim/atom] ~/.zshrc

Add the following line:

export JAVA_HOME=$(/usr/libexec/java_home -v 17)

Update shell profile

source ~/.zshrc
