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

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.
