How do I make IntelliJ IDEA 8.1.x ignore an item in .gitignore

Question

I enjoy Git support in Intellij IDEA 8.1.3. I've been doing some Grails Development on Linux with it.

IDEA seems to be ignoring other files from .gitignore like /tests/reports, etc. but is not ignoring stacktrace.log. In other words changes to stacktrace.log show up in the 'changes' window

The contents of my .gitignore file is:

*.iws
.DS_Store
/out/**

# web application files that are overwritten by "grails upgrade"
#  cf. GRAILS_HOME/scripts/Upgrade.groovy, target( upgrade )
/web-app/WEB-INF

# IDE support files that are overwritten by "grails upgrade"
#  cf. GRAILS_HOME/scripts/CreateApp.groovy, target( createIDESupportFiles )
# to be specific, you could replace "/*" below with your project name,
#  e.g. "foobar.launch" (no slash)
.classpath
.project
.settings
/*.launch
/*.tmproj

# logs
stacktrace.log
/test/reports

# project release file
*.war

/classes

Am I missing something obvious?
How do I make IDEA 8.1.3 ignore all items from .gitignore?

Answer 1

I added the .gitignore while stacktrace.log was still in the repository. When I updated the .gitignore, I expected IDEA to ignore stacktrace.log.

On the command-line when I ran git status I wouldn't see anything for stacktrace.log, but it was showing up as changed in the IDEA Changes window/tab. After I deleted the stacktrace.log and refreshed in IDEA, it no longer showed in the changes window/tab.

Not that big of a deal really.
