sql-surfer and MikroDel   actually  the answer is not that complicated  You just need to add   export JAVA HOME   usr libexec java home    to your shell profile configuration file  The only question is - which shell are you using  If you re using for example FISH  then adding that line to  profile or  bash profile will not work at all  Adding it to config fish file though will do the trick  Permanently
