Did not find any vendor:variant directory for board

[betai97]

I installed the "Arduino Import Plugin" into MPLAB X, but am seeing the error shown in the below picture when I attempt to run the import plugin for the chipkit WiFire board.

java.lang.IllegalArgumentException: Did not find any vendor:variant directory for board "chipkit_Wifire"

Here are the project settings I'm specifying in the importer:

The project successfully builds using the Arduino IDE using the chipkit-core.

Here are the software versions I'm working with:
MPLAB X - v5.40
chipkit-core - v2.1.0
XC32 compiler - v2.50
Arduino IDE - v1.8.12
Arduino Import Plugin - v1.0.26.141202.2 (downloaded through the MPLAB X Plugin manager)

I've attempted with chipkit-core versions 1.3.0, 2.0.2, 2.0.6, and 2.1.0

When I build this repo from source, I see the same NullPointerException issue mentioned in #37
