invalid source 12??

Hey! I have the project open and finally configured to run. I run it and get an invalid source code 12 error. My googlefu returns nothing... I'm at a loss. I've spent hours just learning configuring intellij to get this project to run where I have the option to run it. And now... I run it and boom. I haven't changed any code. I have tried restarting intellij, reopening the project, redownloading and unzipping a second time. Any clues?

i beleive the source code you are wrote is not compatible with the jdk you are using . you should goto project settings in intelij and check what JDK you are using and if the source code you are using is right .

for example you can't be using jdk 7 while you write code which uses stuff that was only introduced starting from jdk 8 such as "lambda expressions"

" invalid source code 12 erro" this propably means you write code for jdk 12 so make sure you have it installed and configured in intellij
