STS 2.9.1 Generate Controller and Views fails

[PatS]

(Q) What am I doing wrong?

I'm using STS 2.9.1 and playing with some basics (just learning Grails).

To experiment, I tried generating a Controller using both STS and grails command line shown below and
I get the error shown below.

Thanks,
PatS

I think that the generate-controller command assumes you are generating the controller *for* a particular domain class.
So you need to first create the domain class.

"grails create-domain-class Bar".
Then "grails generate-contoller Bar".

Typically before you generate the controller. You would probably add some things to the domain classes (some fields to represent that data of this domain object).

This worked.
I played around with grails around a year ago and I'm relearning how it works.

Sorry for the basic question and thanks for the kind reply.
