What's the reason for “Error:Cannot determine Java VM executable in selected JDK”?

Question

I am using IntelliJ IDEA 13.1.4 and also tried the latest release 14.

Running SBT I get the following error:

Error:Cannot determine Java VM executable in         


        

Answer 1

This happened to me in a multi-language project when my primary module's Project SDK was Python and I was trying to add a secondary module that was JDK (importing an sbt project).

I had to temporarily switch the primary module's Project SDK to JDK in order to add the sbt module. I then had the ability to go back and change each module to the correct SDK.
