Error including the TestApp script in grails

Question

Hello I have a simple script as shown below:

I am getting following error on running this script.

includeTargets << grailsScript("Init")
includeTargets << grailsScript("TestApp")

target(main: "The description of the script goes here!") {
      echo "This is the start"
}

  setDefaultTarget(main)

Environment set to test
Error executing script LocalBuild: TestApp_groovy (wrong name: testApp_groovy)
