我已经在Intellij plattform上开发的Grails（版本2.2.1）Web应用程序中成功安装了Grails插件导出（s。http://grails.org/plugin/export）。我下载的所有插件都在单独的“插件”文件夹中，也是导出插件。
When I run my application i get the following error:
Error processing GroovyPageView: Error executing tag <r:layoutResources>: No module found with name [export]
The relevant content of my *.gsp-view:
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<r:require module="jquery-ui"/>
<r:require module="export"/>
<g:layoutHead/>
<r:layoutResources />
</head>
<body>
<div>
<export:formats formats="['csv', 'excel', 'ods', 'pdf', 'rtf', 'xml']" />
</div>
</body>
What may be the cause of the error/exception?
