我试图从命令行在Windows 7（x64）上运行grails应用程序和插件。我可以在没有插件的情况下运行应用程序，但是当我将插件添加到项目中时，我得到一个带有消息Cannot run program "grails" (in directory "[plugin directory]"): CreateProcess error=2, The system cannot find the file specified的java.io.IOException。 grails / bin文件夹位于我的系统环境路径变量中，并且从插件目录的命令行运行就好了。就好像java环境有自己的路径变量，不包含grails。有什么想法吗？
我已经在下面列出了应用程序的完整输出，并修改了插件项目的路径。我希望今天下午能够向客户演示这个项目，因此非常感谢快速的帮助。
