Question

我使用的是jdk1.6和grails 1.3.4。我按照grails.org站点中的说明设置了JAVA_HOME，GRAILS_HOME和PATH变量。当我执行create-app命令时，出现以下错误：

C：\ grails \ grails-1.3.4＆gt; grails create-app C：\ Users \ Documents \ Grails \ helloworld 欢迎来到Grails 1.3.4 - http://grails.org/ 根据Apache Standard License 2.0获得许可 Grails home设置为：C：\ grails \ grails-1.3.4

Answer 1

create-app： Grails的起点。此命令创建Grails应用程序，并要求用户指定应用程序名称。然后根据输入的应用程序名称创建执行命令的目录中的子目录。

执行此命令的正确方法：

使用命令提示符
输入“grails create-app helloworld”
将创建一个子目录“helloworld”作为工作区目录

Grails错误执行create-app
