   set -gx PATH $JAVA_HOME/bin $PATH  
end

function removeFromPath

Thank you, you saved my day!

THANK YOU!

Thanks, that was very helpful.

I added another gist to list the versions you have installed (v simple compliment to your gist). Ok maybe overkill but well i forget the command and you don't have to go look in the dirs.

FYI: I enhanced the script to be able to pick versions (with a -t flag) that might be the same but from different vendors as well (Oracle, OpenJDK ...) .
