(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
      }
    }
The command can then be run with:
    grails my-example
Or as a Gradle task:
    gradle myExample
Note that the plugin should be on both the build classpath and the runtime classpath in `build.gradle`:
    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 the database etc. | Quick Reference (hide)
