Hibernate Grails模式导出生成“0”；未找到线程绑定请求"；错误

我正在尝试使用Grails2.1.1在一个相当大的已建立项目上运行

grails模式导出。不幸的是，我收到以下错误消息：

| Error Error executing script SchemaExport: java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

Application context shutting down...

这就是stacktrace的冗长

一个显而易见的问题是：如何消除这个错误

不太明显的问题是：为什么grails首先要在模式导出上处理标记库？
脚本似乎在其绑定中找到
out
属性，并试图在执行
println
方法时使用该属性。出于某种原因，
out
属性似乎与taglibs绑定在一起。这个
println
似乎是无关的-我会编辑SchemaExport.groovy的第57行来注释它，然后再试一次。或者，您可以尝试编辑它以删除
out
参数，或将其重置为
System.out
在
println
之前

至于taglib上的为什么，不知道。在一个最小的项目上运行这个命令并不会重现这个问题，也不会因为这个项目中的任何上游脚本而让我感到难堪。我想我会检查一下你的配置在这方面是否有什么有趣的地方
