Git如何實現(xiàn)checkout遠(yuǎn)程tag

這篇文章主要介紹了Git如何實現(xiàn)checkout遠(yuǎn)程tag，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教

拉取項目

執(zhí)行命令git clone：

git clone git@github.com:secbr/nacos.git

查看遠(yuǎn)程tag

執(zhí)行命令git tag：

appledeMacBook-Pro-2:nacos apple$ git tag
0.2.1
0.2.1-RC1
0.3.0
0.3.0-RC1
0.4.0
...

此時可找到需要拉取的tag名稱。

checkout需要的tag

執(zhí)行命令git checkout：

(base) appledeMacBook-Pro-2:nacos apple$ git checkout 2.0.2
Note: switching to '2.0.2'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

? git switch -c <new-branch-name>

Or undo this operation with:

? git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at 1fac5c833 Merge pull request #6052 from alibaba/develop

其中2.0.2為tag（分支）名稱。

通過git branch命令可以查看當(dāng)前的分支情況：

(base) appledeMacBook-Pro-2:nacos apple$ git branch
* (HEAD detached at 2.0.2)
? develop

通過此種方式，獲得的分支Head處于游離狀態(tài)，我們可以很方便地在歷史版本之間互相切換，比如需要回到某次提交，直接checkout對應(yīng)的 commit id或者tag名即可。

但在這個基礎(chǔ)上的提交會新開一個匿名分支！也就是說我們的提交是無法可見保存的，一旦切到別的分支，游離狀態(tài)以后的提交就不可追溯了。

解決辦法就是新建一個分支保存游離狀態(tài)后的提交。

checkout作為一個分支

執(zhí)行g(shù)it checkout -b tagName (將tag checkout出去作為一個branch)：

(base) appledeMacBook-Pro-2:nacos apple$ git checkout -b tag-2.0.2
Switched to a new branch 'tag-2.0.2'
(base) appledeMacBook-Pro-2:nacos apple$ git branch
? develop
* tag-2.0.2
(base) appledeMacBook-Pro-2:nacos apple$ git checkout -b tag-2.0.2
Switched to a new branch 'tag-2.0.2'
(base) appledeMacBook-Pro-2:nacos apple$ git branch
? develop
* tag-2.0.2

在游離狀態(tài)下的tag中執(zhí)行g(shù)it checkout -b tag-2.0.2來新建一個分支。

當(dāng)然上述checkout tag和checkout tag作為一個分支，可以合并成一個命令：

(base) appledeMacBook-Pro-2:nacos apple$ git checkout -b tag-1.4.2 1.4.2
Switched to a new branch 'tag-1.4.2'

上述命令，將遠(yuǎn)程版本為1.4.2的tag，新建一個本地分支，名稱為tag-1.4.2。

添加遠(yuǎn)程倉庫

(base) appledeMacBook-Pro-2:nacos apple$ git remote add tag-2.0.2 git@github.com:secbr/nacos.git

push并設(shè)置upstream

(base) appledeMacBook-Pro-2:nacos apple$ git push
fatal: The current branch tag-2.0.2 has no upstream branch.
To push the current branch and set the remote as upstream, use

? ? git push --set-upstream origin tag-2.0.2

(base) appledeMacBook-Pro-2:nacos apple$ git push --set-upstream origin tag-2.0.2
Total 0 (delta 0), reused 0 (delta 0), pack-reused 0
remote:
remote: Create a pull request for 'tag-2.0.2' on GitHub by visiting:
remote: ? ? ?https://github.com/secbr/nacos/pull/new/tag-2.0.2
remote:
To github.com:secbr/nacos.git
?* [new branch] ? ? ? ? ?tag-2.0.2 -> tag-2.0.2
Branch 'tag-2.0.2' set up to track remote branch 'tag-2.0.2' from 'origin'.

以上為個人經(jīng)驗，希望能給大家一個參考，也希望大家多多支持腳本之家。
