grails - 执行创建应用程序时出现Grails错误

Question

我正在使用jdk1.6和grails 1.3.4。我已经按照grails.org网站中的说明设置了JAVA_HOME，GRAILS_HOME和PATH变量。当我执行create-app命令时，出现以下错误:

Answer 1

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.

执行此命令的正确方法:

使用命令提示符

浏览到您的工作区目录

输入“grails create-app helloworld

将创建一个子目录“helloworld”作为您的工作区目录
