Grails - Interactive Mode

Description

It runs the JVM and provides the commands for quicker execution. Type the grails at command line to activate the interactive mode and use the TAB completion to specify the different command types.

D:\Projects\helloworld>grails
grails>

You can also create a service by using the below command:

 
grails> create-service [name]

For instance, we will create a service class "team" and "players" will be the associated unit test for the given base name:

D:\Projects\helloworld>grails
grails> create-service team.players
| Rendered service class to grails-app/services/team/PlayersService.groovy
| Rendered service class to src/test/groovy/team/PlayersServiceSpec.groovy
grails>

The above command creates the service under grails-app/services folder and its associated unit test of a service will be created under src/test folder.

You can list down the other commands to run external process by using the below command:

 
grails> ls
Unmatched argument at index 0: 'ls'
