Question

我正在测试grails 2.3.0，但是当我创建战争（prod，test，dev）并尝试启动tomcat（7.0.42）时总会遇到此异常：

    2013-09-25 18:23:03,448 [localhost-startStop-1] ERROR context.GrailsContextLoader  - Error initializing the application: No signature of method: groovy.xml.streamingmarkupsupport.StreamingMarkupWriter.attributeValue() is applicable for argument types: () values: []

任何想法？

Answer 1

您的grails类路径中可能有多个相同lib的jar版本。尝试删除

rm -Rf ~/.grails

rm -Rf ~/.m2 

grails clean

grails run-app

如果没有成功，请尝试在grails项目jar上运行jarscan以查找重复的类定义。
