git解决冲突与merge

                     

git冲突的场景与其他SCM工具一样，我在这边修改了文件a，同事也修改了文件a。同事比我先提交到仓库中，那么我pull代码时就会报错：

$ git pullremote: Counting objects: 39, done.remote: Compressing objects: 100% (30/30), done.remote: Total 39 (delta 13), reused 0 (delta 0)Unpacking objects: 100% (39/39), done.From https://code.csdn.net/lincyang/androidwidgetdemo   d3b2814..5578b8c  master     -> origin/masterUpdating d3b2814..5578b8cerror: Your local changes to the following files would be overwritten by merge:    app/src/main/AndroidManifest.xml    app/src/main/java/com/linc/skill/screenswitch/ScreenSwichActivity.javaPlease, commit your changes or stash them before you can merge.Aborting

而此时我又不顾这个错误，将我的代码add并commit，然后push时报如下错：

To https://code.csdn.net/lincyang/androidwidgetdemo.git ! [rejected]        master -> master (non-fast-forward)error: failed to push some refs to 'https://code.csdn.net/lincyang/androidwidgetdemo.git'hint: Updates were rejected because the tip of your current branch is behindhint: its remote counterpart. Integrate the remote changes (e.g.hint: 'git pull ...') before pushing again.hint: See the 'Note about fast-forwards' in 'git push --help' for details.

然后我有执行了git pull：

$ git pullAuto-merging app/src/main/java/com/linc/skill/screenswitch/ScreenSwichActivity.javaCONFLICT (content): Merge conflict in app/src/main/java/com/linc/skill/screenswitch/ScreenSwichActivity.javaAuto-merging app/src/main/AndroidManifest.xmlCONFLICT (content): Merge conflict in app/src/main/AndroidManifest.xmlAutomatic merge failed; fix conflicts and then commit the result.

那么既然两个文件冲突，我就可以借助mergetool来搞定它。我安装了meld作为代码比对工具，那么它理所当然也就成为我的mergetool了。

$ git mergetoolThis message is displayed because 'merge.tool' is not configured.See 'git mergetool --tool-help' or 'git help config' for more details.'git mergetool' will now attempt to use one of the following tools:meld opendiff kdiff3 tkdiff xxdiff tortoisemerge gvimdiff diffuse diffmerge ecmerge p4merge araxis bc3 codecompare emerge vimdiffMerging:app/src/main/AndroidManifest.xmlapp/src/main/java/com/linc/skill/screenswitch/ScreenSwichActivity.javaNormal merge conflict for 'app/src/main/AndroidManifest.xml':  {local}: modified file  {remote}: modified fileHit return to start merge resolution tool (meld): Normal merge conflict for 'app/src/main/java/com/linc/skill/screenswitch/ScreenSwichActivity.java':  {local}: modified file  {remote}: modified fileHit return to start merge resolution tool (meld):

merge完成后，执行git status发现有些文件做了修改，那么把这些文件提交 吧，就把这次commit作为一次merge操作吧。

$ git commit -m "merge"[master 978aa1f] merge$ git pushCounting objects: 64, done.Delta compression using up to 4 threads.Compressing objects: 100% (25/25), done.Writing objects: 100% (33/33), 3.81 KiB | 0 bytes/s, done.Total 33 (delta 15), reused 0 (delta 0)To https://code.csdn.net/lincyang/androidwidgetdemo.git   5578b8c..978aa1f  master -> master$ git pullAlready up-to-date.

至此，本次冲突解决完毕。

如果希望保留生产服务器上所做的改动,仅仅并入新配置项, 处理方法如下:

git stashgit pullgit stash pop
