How can I add an exception to .gitignore, like "ignore all the .dll files BUT myfile.dll"?
回答1:
Use ! to negate the pattern:
*.dll
!myfile.dll
回答2:
If you want to ignore whole folder, except some specific files, then write:
MyFolder/*
!MyFolder/CoolFile.txt
This won't work:
MyFolder/
!MyFolder/CoolFile.txt
回答3:
You can also ignore folders like
!src/main/resources/archetype-resources/**/*
you can also ignore nested folder with patterns like
!**/src/test/resources/**/*
回答4:
You can have several .gitignore files working together in a hierarchical manner to achieve your goal.
At the root level you may have:
root
*.dll
inside the folder having the myfile.dll you can add another .gitignore file like so:
root/lib/folderwithMyFiledll
!myfile.dll

An optional prefix "!" which negates the pattern; any matching file excluded by a previous pattern will become included again. Put a backslash ("\") in front of the first "!" for patterns that begin with a literal "!", for example, "!important!.txt". It is possible to re-include a file if a parent directory of that file is excluded if certain conditions are met. See section NOTES for detail.

I did this because I have a folder called /modules that I want to ignore, except everything in the /modules/custom folder. This worked for me. Now my custom modules will get synced to GitHub.
/modules/*
!/modules/custom/
