More info, this is Mac, and groovy is installed by brew install groovy, and there is no GROOVY related environment variables created:

$ env | grep GROOVY | wc
      0       0       0

Answer 1

I suggest to use skdman to manage your Groovy installations, this will create the GROVY_HOME env variable for you, the other way is to find the location of your groovy installation and create a GROVY_HOME env pointing to bin location inside Groovy folder.
