I am running Eclipse - Indigo and have a project configured for EGit that uses Gradle to build. Today, when I noticed in the eclipse package explorer, the build.gradle file now has a red slash through the icon:

Where did the little red slash come from, and what does that mean? Is this something like this (I donβt think the file is displayed in git status from the command line, and this red icon doesnβt appear in settings, Team, Git, Label Decorations)? I have never noticed this until today, which makes me believe that until today it has not appeared.
EDIT: Is there a chance that .gitignore contributes to eclipse's confusion? Here is the contents of my .gitignore / Test output / logs
# Gradle .gradle /build
