Grails + GAE - Issue using app.servlet.version=2.5

Question

Updating the servlet version in application.properties to 2.5 has no affect on the generated web.xml. The generated web.xml is still version 2.4. I'm using Grails 1.2.1.

app.servlet.version=2.5

Also, if I try to execute "run-app" I get the exception below:

Running Grails application..
Starting AppEngine generated indices thread.
Starting reload monitor thread.

Any ideas how to resolve these issues?

Answer 1

Have you tried doing a grails clean after making the change in servlet version? At least that works on my machine (grails 1.2.0).
