如何正確執行git merge / pull：你還沒有完成你的合並（MERGE_HEAD存在）

Question

我是Git的新手，無法理解如何使用Git。 我一直在使用CVS，因此需要為Git學習一些學習曲線。 這就是我所嘗試的一切

現在我只更改了兩個文件PromoServiceImpl.java和build.sql。 但是合並有問題從“產品”分支改變了。

您看到的剩余文件（如ApiServiceImpl.java等）是來自其他用戶的更改，但我不確定此處的表示是否表明我已更改它們。 問題是它在早期的pull命令中合並了，現在它希望我提交它們？

無論我遵循什么命令流（即使在谷歌搜索之后），我都會看到以下錯誤：

您尚未完成合並（MERGE_HEAD存在）請在合並之前提交更改。

這是我遵循和輸出的命令序列（試圖通過插入新行供每個人閱讀來使其漂亮）。 即使在重新從存儲庫中進行更改之后，這個錯誤也會回來，所以我確信我做錯了而不是git的一些問題。

Pull is not possible because you have unmerged files.
Please, fix them up in the work tree, and then use 'git add/rm <file>'
as appropriate to mark resolution, or use 'git commit -a'.

Answer 1

這里有幾件事情。 它有助於了解發出各種Git命令時會發生什么。

pull命令（如在git pull ） 導致 fetch后跟merge 。 所以，當你做了pull

kamal@kamal-Lenovo-G470:~/git/TryGit$ git pull origin product

Git試圖從默認的遠程存儲庫中獲取更改

From ssh://192.168.2.251/TryGit
 * branch            product    -> FETCH_HEAD

並將它們合並。

Auto-merging TryGitResources/build/build.sql

這樣做會遇到沖突

CONFLICT (content): Merge conflict in TryGitResources/build/build.sql
Automatic merge failed; fix conflicts and then commit the result.

Git維護這3個版本的文件，等待合並 - 你的更改，更改和共同的祖先。 引入的版本暫時存儲在MERGE_HEAD中。

您可以通過git diff調用查看git diff 。 此時，您需要修復Git無法自動解決的沖突。 一旦修復它，只需執行通常的git add然后執行git commit 。 在commit命令的手冊頁的examples部分中也解釋了此過程。

哦! 看來你有一個名為Adding的文件 。 請注意， git status命令以。結尾

# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#   Adding

當您要求Git跟蹤目錄時（例如當您執行git init . ）會發生這種情況。 從那時起，Git監控指定位置的變化。 上面說的是“我看到你添加了一個名為Adding的文件。我對它的了解不多（它沒有跟蹤）。” 一旦你添加它，Git就會開始跟蹤變化（可以告訴你隨着時間的推移發生了什么變化）。
