Java version does not apply on Mac

Question

I am trying to set my machines javac version to 11 from 18.0.2 and I'm doing the following steps

open ~/.zshenv
export JAVA_HOME=$(/usr/libexec/java_home -v11)
source ~/.zshenv

When I check the version, I still get it as 18.0.2. Not sure what I am doing wrong here. Could someone please help me with this? Been stuck on this forever.

Check your PATH variable or try where is javac. Sounds like the path is pointing to the v18 executable. — kiwiron, Oct 28 '22 at 20:14
@kiwiron `echo $PATH` returns this `/Users/xxx/bin:/usr/local/bin:/Users/xxx/bin:/usr/local/bin:/usr/local/bin:/Users/xxx/bin:/usr/local/bin:/opt/homebrew/bin:/opt/homebrew/sbin:/usr/local/bin:/Users/xxx/bin:/usr/local/bin:/Library/Frameworks/Python.framework/Versions/3.10/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin` — boomchickawawa, Oct 28 '22 at 20:24

What works like a charme for me is using jenv: https://www.jenv.be/

With jenv you can also switch between different Java versions.

Before using jenv, I relied on the Maven toolchains plugin: https://maven.apache.org/plugins/maven-toolchains-plugin/

Thus, I actually never really worried about JAVA_HOME on MacOS. Maybe one of these options also is an alternative for you.

Thanks for the answer. I was able to change the version using jenv, however when I run the command `javac --version` I get `18.0.2` – boomchickawawa Oct 30 '22 at 20:25
Nvm I just had to refresh the terminal. Thank you sir, spent countless hours on this! – boomchickawawa Oct 30 '22 at 20:27

still spits the old version when I do `echo $JAVA_HOME` `/Library/Java/JavaVirtualMachines/jdk-18.0.2.jdk/Contents/Home` – boomchickawawa Oct 30 '22 at 20:08

I don't know if this typo is only in your question here, but you need to put a space between "-v" and "11":

export JAVA_HOME=$(/usr/libexec/java_home -v 11)
