Grails gant script to run test cases first and then run the application but It is giving cliScriptException

Question

I am writing a GANT script in grails to run unit test cases first and then it will run the if unit test cases passed .

My Script is

includeTargets << grailsScript("_GrailsInit")
includeTargets << grailsScript("_GrailsSettings")
includeTargets << grailsScript("_GrailsClean")
includeTargets << grailsScript("_GrailsTest")
includeTargets << grailsScript("_GrailsRun")
import org.codehaus.groovy.grails.cli.GrailsScriptRunner as GSR
//includeTargets << new File ( "${grailsHome}/scripts/RunApp.groovy" )

/*target(customRun: "The description of the script goes here!") {
    // TODO: Implement script here
    depends(checkVersion, configureProxy, parseArguments, cleanTestReports)
    runApp()
    //runApp()
}*/

target(customRun: "The description of the script goes here!") {
    // TODO: Implement script here
    depends(checkVersion, configureProxy, parseArguments, cleanTestReports)
    System.setProperty("grails.env", "test")
    allTests()
    System.setProperty("grails.env", "development")
    runApp()
}

setDefaultTarget(customRun)

But I am getting scriptException once the test report is generated . I am not sure what wrong is in my script .

Exception is as
