如何快速使用新分支覆盖老分支

来自stackoverflow的问题:

How do I resolve a git merge conflict in favor of pulled changes?

Basically I need to remove all conflicting changes from a working tree without having to go through all of the conflicts with a git mergetool while keeping all conflict-free changes. Preferably doing this while pulling, not afterwards.

如何在pull代码的时候就从A分支合并所有的代码并且解决冲突合并到B分支

git pull -s recursive -X theirs origin develop_next
