git does not recognize exe file

Question

I'd like to upload NuGet.exe to github but all exe files are not listed to my local repository.

I did upload NuGet.exe file about two weeks ago at another project repo, but now I cannot upload any exe file at all. There is no global .gitignore that I specially defined.

below code is my .gitignore file. what am I missing?

-- EDIT --

same files under .nuget/ directory .config and .targets files are well treated. I can check git ls-files --others -i --exclude-standard gives NuGet.exe is ignored, but I don't know which rule makes it.

Answer 1

First, you can check if a file is locally ignored ion your repo with git check-ignore:

git check-ignore -v -- yourFile

Second, you can force to add that file (bypassing any ignore rule):

git add -f yourFile
