javac: invalid target release: 1.8


I recently downloaded JDK that comes bundled with NetBeans. I then got to find out that my JavaFx project, that I have been developing in Java 1.7 won't compile in Java 1.8, and so I stepped down my JDK to 1.7. Still I can't get it to work/ compile. I get this error:

javac: invalid target release: 1.8
Usage: javac <options> <source files>

I'm really stuck and would greatly appreciate any help.

Accepted Answer

if you are going to step down, then change your project's source to 1.7 as well,

right click on your Project -> Properties -> Sources window 

and set 1.7 here

note: however I would suggest you to figure out why it doesn't work on 1.8

For IntelliJ14 you may have to change the bytecode version w.r.t. the JDK you are using (in the global settings):
