运行grails应用程序的错误

Question

我是Grails新手。我已经安装了grails 2.0.3版本。每当我运行我的应用程序时，它会给出相同的错误我无法找到背后的原因。我在下面给出完整的堆栈跟踪：

| Packaging Grails application..... 
[Fatal Error] plugin-list-grailsCentral.xml:14058:53: XML document structures must start and end within the same entity.

请帮助我，这是造成这种情况。提前致谢。

Answer 1

Stacktrace说Access denied for user 'root'@'localhost'。

确保您在localhost上运行MySQL实例，该实例的用户root没有密码（因为stacktrace说您没有指定任何密码）。你可以通过调用一下：

> mysql -u root --password='' -D %YOU DATABASE NAME%
