git上传(本地和远程有冲突时)

一. 冲突的产生:在上次git同步(上传)之后,本地和远程均有更改

二. 处理

1. 丢弃本地,采用远程:

    git checkout 冲突文件及其路径

    如: git checkout bzrobot_navigation_meta_packages/map_server/src/access_map_server.cpp

2. 人为合并( git mergetool)本地和远程代码 (思路:先提交没有冲突的部分,再人为合并,再提交冲突的部分,最后将所有改动push上去)

    1). git pull: 提示冲突

    2). 提交(git add --all; git commit)

    3). git pull

    4). git mergetool

    5). git pull
    6). git commit 
         [216-fixed-area-walk d228a46] Merge branch ‘216-fixed-area-walk‘ of 192.168.1.51:IGV/IGV01-SW into 216-fixed-area-walk

    7). git add --all
    8). git commit
    9). git push origin 216-fixed-area-walk

以下是一次情况2的实际操作过程:
