Spring model validation failing in 8.1.3

Hi,

Since I upgraded from 8.1.2 to 8.1.3 I'm unable to rebuild my grails project without errors. The errors occur during the "Validate Spring Model" step of the build and produce the following errors when validating the generated file:

C:\dev\apps\rivendell-grails-1.1.1\web-app\WEB-INF\applicationContext.xml
    Error:Error:line (37)Cannot find matching files
    Error:Error:line (9)Cannot resolve file 'grails.xml'
    Error:Error:line (37)Cannot resolve directory 'grails-app'

I've appended the content of this file to the end of my message. I can't say for sure that the problem was caused by the upgrade to 8.1.3, because I hadn't built the project for a while before upgrading. Presumably I could use the "Exclude from Compile" option on this file to workaround the problem, but I'd like to know if there's another solution, or something wrong with my project setup?

Cheers,
Don
