How can Services be be accessed within Grails scripts?

The documentation on create-script/run-script is minimal so I'm wondering if it's possible to to inject/use domain classes in grails scripts. In a normal grails class I could inject a service like:

def myService

but I'm not sure where is would go inside of a grails script

When using Grails 2.4.3, here is my complete solution:

First, as is mentioned in "Error loading plugin manager: TomcatGrailsPlugin" on Grails 2.3 Database Migration by Tai, change the tomcat build type in buildConfig.groovy to compile instead of build like so:

compile ':tomcat:7.0.42'

This avoids the “Error loading plugin manager: TomcatGrailsPlugin” error which would otherwise occur every time you run your script.

Next, create scripts/DoSomething.groovy

includeTargets << grailsScript("_GrailsInit")
includeTargets << grailsScript("_GrailsBootstrap")
includeTargets << grailsScript("_GrailsClasspath")

target(main: "An example script that calls a service") {
    depends(bootstrap)

    def someService = appCtx.getBean("someService") // look up the service
    someService.runReportOrSomething() // invoke a method on the service
}

setDefaultTarget(main)

The above code causes the entire Grails stack to initialize, so all your services, domain classes, etc. will be set up for you.

Finally, to run it, do this:

grails prod do-something --stacktrace -echoOut

You might be tempted to do "grails run-script scripts/DoSomething.groovy but for whatever reason that doesn't seem to work.

To use domainClasses in scripts:

includeTargets << grailsScript("_GrailsBootstrap")

at the top

Then within function requiring access to add:

depends(bootstrap)

def myDomainClass = grailsApp.classLoader.loadClass("myapp.MyDomainClass")
def myDomainClassList = myDomainClass.list()

There is lots of information on all of this in The Definitive Guide to Grails 2
