需要在Eclipse的Classpath上创建一个GRAILS_HOME的变量.

http://grails.5d6d.com/thread-90-1-1.html

做了一个总结，谢谢楼上指点

請添加一個名為GRAILS_HOME的Eclipse變量：
1、右擊Project並選擇“Property”。
2、在右側菜單中選擇“Java Build Path”。
3、點擊右側“Add Variable...”按鍵。
4、點擊左下方“Configure Variables...”按鍵。
5、選擇左側樹菜單項“Classpath Variables”，在“Classpath Variables面板中單擊“New...”按鍵。
6、在“Name”欄中輸入“GRAILS_HOME”，在“Folder”欄中定位Grails安裝目錄位置。
7、點擊“OK”按鍵，完成。
