執行create-app的Grails錯誤

我正在使用jdk1.6和grails 1.3.4。我已經按照grails.org網站中的說明設置了JAVA_HOME，GRAILS_HOME和PATH變量。當我執行create-app命令我碰到下面的錯誤：執行create-app的Grails錯誤

這是一個錯誤 - 在Grails的最新版本中，如果您未指定它，腳本將提示您輸入應用程序名稱。 – 2012-09-16 22:16:47

create-app: The starting point for Grails. This command creates a Grails application and requires the user to specify the application name. A subdirectory within the directory the command was executed from is then created based on the entered application name.

執行此命令的正確方法：使用命令提示符

瀏覽到您的工作空間目錄
類型「Grails的創造，應用的HelloWorld
將創建子目錄「helloworld」作爲您的工作空間目錄
