Adding additional comments so that folks know to use the integration tool rather than copying this for better results.

Those files should be in Global/ templates

This entry should be (and is) rather in Global/JetBrains.gitignore

Only files under /web-app/WEB-INF/classes (build output) should be ignored by Git. Grails generates a few default (unchanging) files (applicationContext.xml, sitemesh.xml, a bunch of *.tld) that need to be there for some plugins to function properly (e.g., grails war).

/web-app/WEB-INF is already ignored, no need to specify sub-directories
