API / Apache Grails Interview questions

How do you create a new Grails application using Grails Forge?

  1. Visit start.grails.org and choose the application's group and package name, similar to filling out a form on Spring Initializr.
  2. Select a profile (such as "web" for a traditional server-rendered application or "rest-api" for a JSON-focused backend), which determines the base set of dependencies and starting project layout.
  3. Add any desired features or plugins (database driver, Spring Security, asset pipeline) from the options Grails Forge offers, so they're pre-wired into the generated build file rather than added by hand afterward.
  4. Download the generated project archive, which already includes the Grails Wrapper (grailsw/grailsw.bat), so no separate CLI installation is required.
  5. Run ./grailsw run-app (or the platform-appropriate wrapper command) from the extracted project directory, which downloads the pinned CLI version on first run and starts the application locally.

The end result is a working, runnable skeleton application with the chosen profile's conventions already in place — a developer's first real work is filling in domain classes and business logic, not assembling the initial project scaffolding by hand.

What does selecting a "profile" on Grails Forge determine?
Does a developer need to separately install a specific Grails CLI version before running a Grails Forge-generated project?
