Environment

Release : Clarity releases working on Java 11

Resolution

You have to use Java 11 with XOG for it to work. Go to Control Panel - System - Environmental variables and ensure you have set up Java 11 in the PATH as well as JAVA_HOME in the environmental variables. 

Then close and reopen Command Prompt and try again and this should work
