英文:
Why this?: \dotnet\ was unexpected at this time
问题
在Windows 11上，这是我的批处理文件：
if "%orig_path%"=="" (
set "orig_path=%path%"
) else (
path %orig_path%
)
path %path%;D:\.jdks\corretto-1.8.0_322\bin
set "JAVA_HOME=D:\.jdks\corretto-1.8.0_322"
（我这样做是因为我经常需要在Java 8和11之间切换。）
在第一行，我收到这个错误消息：在此时间点上，\dotnet\ 是意外的。
这是我当前路径中的两个元素中的一个的引用：
...C:\Program Files\dotnet\;C:\Program Files (x86)\dotnet\;...
我怀疑问题不是空格字符，因为在这些之前还有几个元素使用了空格字符，所以问题很可能是围绕 x86 的括号。
（我没有权限更改路径的这部分。）
我已经读到可以通过将 if 语句更改为以下内容来解决此问题：
if [%orig_path%]==[] ...
但这也不起作用。这会给我带来以下错误：
在此时间点上，C:\WINDOWS 是意外的。
我还读到应该在文件开头添加 SETLOCAL ENABLEDELAYEDEXPANSION，但那没有改变任何事情。
如何才能让这个工作？
英文:
On Windows 11, here's my batch file:
if "%orig_path%"=="" (
set "orig_path=%path%"
) else (
path %orig_path%
)
path %path%;D:\.jdks\corretto-1.8.0_322\bin
set "JAVA_HOME=D:\.jdks\corretto-1.8.0_322"
(I do this because I often need to switch between Java 8 and 11.)
On the very first line, I get this error message: \dotnet\ was unexpected at this time.
This is a reference to one of two elements in my current path:
...C:\Program Files\dotnet\;C:\Program Files (x86)\dotnet\;...
I doubt the problem is the space character, because several elements before these also use a space character, so the culprit is probably the parentheses around x86.
(I'm not authorized to change that part of my path.)
I have read that I can fix this by changing the if statement to this:
if [%orig_path%]==[] ...
but that doesn't work either. That gives me this error:
C:\WINDOWS was unexpected at this time.
And I've read that I should say SETLOCAL ENABLEDELAYEDEXPANSION at the start of the file, but that didn't change anything.
How can I get this to work?

以下是您要翻译的内容：
Easy-peasy.
Your code would be resolved to:
if "Program Files (x86)\dotnet\"=="" (
set "orig_path=%path%"
) else (
path Program Files (x86)\dotnet\...
)
and that ) closes the if; cmd doesnt know what to do with the \dotnet\... so complains.
To fix:
if "%orig_path%"=="" (
set "orig_path=%path%"
) else (
path "%orig_path%"
)
or my preference
if defined orig_path (
path "%orig_path%"
) else (
set "orig_path=%path%"
)
