resource plugin error when upgrading from grails 2.3.8 2.4

Question

Im following the docs trying to upgrade my project from 2.3.8 to 2.4, but I am encountering these error(s)

localhost-startStop-1] ERROR resource.ResourceProc         


        

Answer 1

As it says in documentation no longer you need to use resource plugin:

As of Grails 2.4 the resources plugin has been replaced with the asset-pipeline

now you could use asset plugin instead. use this link and you can easily upgrade your resources from 2.3.8 to 2.4.

Answer 2

Your web.xml may still contain references to the sitemesh filter:

http://grails.org/doc/2.4.3/guide/upgradingFrom23.html

The Sitemesh servlet filter has been removed and the GSP layout feature is now handled by GrailsLayoutView.

Rename the src/templates folder to src/templates-old, then run grails install-templates. If you previously customised your web.xml, you will need to edit the generated web.xml to make these changes again.

Answer 3

This is an issue in the jQuery-ui plugin in JqueryUiPluginResources.groovy in the following two lines:

def appCtx = org.codehaus.groovy.grails.commons.ApplicationHolder.application.mainContext

def plugin = appCtx.pluginManager.getGrailsPlugin('jquery-ui')

The fix for this is present in the following commit: https://github.com/gpc/grails-jquery-ui/pull/13
