EduTools : Use JDK instead of JRE

First of all can't say how much I appreciate the tool.

I'm just learning java and come from a background of more c code, cobol, scripting, etc.

I'm trying to use the EduTool in Intellij to learn java and eventually work on some projects.

The whole environment is very different so I find myself stumbling through what is probably 2nd nature to all other people.  

Anyways my issue is that I can't figure out how to run the task.java associated to a particular lesson.

I'm just at the beginning where I'm putting just putting comments in task.java, and if I hit the green run arrow at the top it says "unable to execute task theory".

If I go to the run drop down menu and hit run It pops up a a window where my only choice is 0.edit configuration.

When I choose that.. well I get a window with a lot of defautl configurations and I've no idea what I should fill out.

I also tried the build option and got the message Please, use JDK instead of JRE for Gradle importer. Open Gradle Settings 

Which I'm really not 100% sure what is wrong with the settings.  it look right as far as I can tell.

Sincerely - thanks.
