The Grails Framework 6.0.0

(Quick Reference) ## create-command ### Purpose The `create-command` command creates a new Grails Gradle task and shell command that can be run with the `grails` command from a terminal window. ### Examples The command:
    grails create-command MyExample
Creates a class called `grails-app/commands/PACKAGE_PATH/MyExampleCommand.groovy` such as:
    import grails.dev.commands.*

    class MyExampleCommand implements ApplicationCommand {

      boolean handle(ExecutionContext ctx) {
          def dataSource = applicationContext.getBean(DataSource)
          return true
      }
    }
Commands can be executed with the `runCommand` command.
    grails run-command my-example
Or as a Gradle task:
    gradle runCommand -Pargs="myExample"
If the command you are executing is defined in a plugin that you have declared a dependency on, then you can execute the command in short form like so:
    grails my-example
Or as a Gradle task:
    gradle myExample
The plugin is required be on both the build classpath and the runtime classpath in `build.gradle` in order for the short form to work:
    buildscript {
      ...
      dependencies {
        classpath "org.grails.plugins:myplugin:0.1-SNAPSHOT"
      }
      ...
      dependencies {
        runtime "org.grails.plugins:myplugin:0.1-SNAPSHOT"
      }
    }
### Description In order to separate the code generation and build layer, in Grails 3.x scripts created with `create-script` do not have access to the running application instance. Instead, Grails 3.x features a new concept called an ApplicationCommand that is invoked via Gradle to perform tasks such as interact with classes in the runtime. | Quick Reference (hide)
