pyjnius KeyError: 'JAVA_HOME' on Pycharm

Hello there,
I am trying to compile code with jnius in my pycharm python compiler but I get an error like the following. I installed Java with oracle and installed jnius on pycharm but the problem did not change. The answer I get when I do this command is:
$ echo $JAVA_HOME
   -->>/usr/lib/jvm/java-8-openjdk-amd64

I'm waiting for your help
