Grails resources not found errors

Question

I have a grails application which stops working after installing shiro plugin for authentication. After installation I got the following error.

Error 2014-03-27 11:08:35,985 [localhost-startStop-1] ERROR spring.GrailsRuntimeConfigurator  - [RuntimeConfiguration] Unable to load beans from resources.groovy

I know resources are not found here but I have done nothing with the resources and directories, just installed the plugin and this error comes to show. I also tried to un-install the plugin and try again but that also did not solve my problem.
