Question

我正在尝试在我的系统上创建一个hello world grails应用程序。我创建了一个全新的grails安装并运行命令grails create-app racetrack但是当我运行我的应用程序时，我收到以下错误：

有谁知道出了什么问题或我能做些什么来解决它？感谢。

我的第一个猜测是你的类路径中有一个冲突的jar。尝试删除任何可能与org/w3c/dom/NamedNodeMap相关的罐子（可能是重复的罐子），例如xerces，xml-api，xalan等。

对于hello world应用程序来说，这不应该发生，但是可以使用它来玩......很好！

Grails hello world，执行bootstraps java链接错误时出错
