Upgrading from Grails 2.3.8 to 2.4.2
When upgrading to Grails 2.4.2 i ran into an issue where the following error message would pop up.
Error creating bean with name 'grailsApplication' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Cannot resolve reference to bean 'grailsResourceLoader' while setting bean property 'grailsResourceLoader'; To solve this issue you need to delete some lines in the <grails-app>/web-app/WEB-INF/applicationContext.xml file.
Delete the following lines:
<property name="grailsResourceLoader" ref="grailsResourceLoader" />
<bean id="grailsResourceLoader" class="org.codehaus.groovy.grails.commons.GrailsResourceLoaderFactoryBean" />
And you should be up and running quickly.
