问题
In my .gititnore I have an entry:
/build
Which works well- the entire directory is ignored by git. Now, I just want to make an exception to this rule and keep this file /build/outputs/mapping/release/mapping.txt in git.
How can I do this?
回答1:
The current rule for gitignore is
It is not possible to re-include a file if a parent directory of that file is excluded.
That means:
- you need to ignore all the files recursively: that is '
**' - exclude all the folders recursively: those are '
**/' - exclude the file you want (which will work because its parent folder is not ignored as well)
Result:
/build/**
!/build/**/
!/build/outputs/mapping/release/mapping.txt
Check what is and is not ignored with git check-ignore -v (the -v is important):
git check-ignore -v -- afile
