Windows 多个for循环用于设置变量，但只有第一个循环产生效果

这是我的Windows批处理文件：

FOR /F %%a IN ('git rev-parse --abbrev-ref HEAD') DO SET branchName = %%a
FOR /F %%a IN ('git rev-list --max-count^=1 %branchName%') DO SET localCommitId = %%a
FOR /F %%a IN ('git rev-list --max-count^=1 origin/%branchName%') DO SET remoteCommitId = %%a

@ECHO branchName = %branchName%
@ECHO localCommitId = %localCommitId%
@ECHO remoteCommitId = %remoteCommitId%

以下是我运行时看到的输出：

>FOR /F %a IN ('git rev-parse --abbrev-ref HEAD') DO SET branchName = %a

>SET branchName = develop

>FOR /F %a IN ('git rev-list --max-count=1 develop') DO SET localCommitId = %a

>SET localCommitId = e4375fa4753b3956e1454020a812cc7591cf606e

>FOR /F %a IN ('git rev-list --max-count=1 origin/develop') DO SET remoteCommitId = %a

>SET remoteCommitId = e4375fa4753b3956e1454020a812cc7591cf606e

branchName = develop
localCommitId =
remoteCommitId =

我不明白为什么

localCommitId

和

remoteCommitId

是空的，尽管打印的

SET

命令将它们设置为非空字符串

---

我猜

git

命令的功能与这个问题无关，因为如果我用

ver

替换它们，我也会遇到同样的问题，我还将添加一些解释。如果键入

set branch

，您将看到

branchName=develope

。这意味着变量实际上将被

%branchName%

调用，并将给出值

develope

更正了下面的代码

FOR /F %%a IN ('git rev-parse --abbrev-ref HEAD') DO SET branchName=%%a
FOR /F %%a IN ('git rev-list --max-count^=1 %branchName%') DO SET localCommitId=%%a
FOR /F %%a IN ('git rev-list --max-count^=1 origin/%branchName%') DO SET remoteCommitId=%%a

@ECHO branchName = %branchName%
@ECHO localCommitId = %localCommitId%
@ECHO remoteCommitId = %remoteCommitId%

尝试删除set命令中的空格，例如：

DO set branchName=%%a

有效！谢谢你可以把它贴出来作为答案。
