有问题的行是：
cleartool rebase -rec %rebaseOptions% -force -abort >> %rebaseLog% 2>&1
这是在 "if %rebase%" 块中，具有讽刺意味的是，它甚至没有被调用。我猜它只是在解析过程中失败了。
谁能明白为什么这可能会给我“此时 2>&1 出乎意料。”错误？
在大多数情况下，引用 %buildLog%、%nightlyLog%、%rebaseLog% 是个好习惯（除非您正在回显这些变量的内容），因为它们中可能有空格或特殊字符。
cleartool rebase -rec %rebaseOptions% -force -abort >> "%rebaseLog%" 2>>&1
如果还不能解决问题，请临时在行上方添加@ECHO ON
如果 %rebase% == 1 (
所以你可以看到发生了什么。
此外，如果您要附加 STDOUT 的输出，您可能也打算附加 STDERR 的输出。如上所示 2>>&1... 虽然那不是你的问题。
我认为问题行是：
163 call %buildDir%scons.bat -k > %buildLog% 2>&1
注释掉或删除 @echo off，我机器上的输出以：
结尾
C:\Users\pwatson\t>rem Build SCONS
C:\Users\pwatson\t>if 0 == 1 sconsCount.exe -clean 1>>C:\_NightlyBuildLogs[=11=]-26-1-213054826_nightly.log 2>&1
2>&1 was unexpected at this time.
C:\Users\pwatson\t> call vgrDevEnv\build\scons.bat -k > 2>&1
这使得标准输出似乎没有目标文件名。这是因为没有使用延迟扩展。在 if 块内，将 %buildLog% 替换为 !buildLog!。
下一个街区也是如此。使用 !cabLog! 而不是 %cabLog%.
我敢肯定你误诊了错误所在。
我认为错误在以下块中：
if %sconsBuild% == 1 (
set buildLog=%NBLDir%\%TIMESTAMP%_build.log
echo buildLog=%buildLog% >> %nightlyLog%
echo Building SCons %buildLog% >> %nightlyLog%
call %buildDir%scons.bat -k > %buildLog% 2>&1
sconsCount.exe >> %buildLog% 2>&1
wxsMissingFileTest >> %buildLog%
SConsBuildReport %buildLog% >> %nightlyLog%
)
请注意，您在块中定义了 buildLog，然后尝试在同一块中使用它。当然，扩展将是空的，因为在解析块时该值不存在。所以这两行
call %buildDir%scons.bat -k > %buildLog% 2>&1
sconsCount.exe >> %buildLog% 2>&1
成为
call vgrDevEnv\build\scons.bat -k > 2>&1
sconsCount.exe >> 2>&1
你有错误。
只需定义块前的值即可。
set buildLog=%NBLDir%\%TIMESTAMP%_build.log
if %sconsBuild% == 1 (
echo buildLog=%buildLog% >> %nightlyLog%
echo Building SCons %buildLog% >> %nightlyLog%
call %buildDir%scons.bat -k > %buildLog% 2>&1
sconsCount.exe >> %buildLog% 2>&1
wxsMissingFileTest >> %buildLog%
SConsBuildReport %buildLog% >> %nightlyLog%
)
其他问题：
- 您的日期字符串中有额外的 space，因为您的作业有不需要的尾随 space。最好在使用 SET 时使用引号，因为这样最后一个引号之后的所有内容都会被忽略，而且您不必担心隐藏尾随 spaces
set "tsyear=%date:~-4%" Everything after the last quote is ignored
即使您修复了尾随 space 问题，您仍然可以在小时值中获得前导 space，因为 %TIME% 将用 space 而不是 0 如果时间在上午 10 点之前。
您应该知道您的 :getTS 例程高度依赖于您的语言环境。例如，它在我的机器上不起作用——它在值中引入了 /。一个简单的搜索产生了更好的方法来以与区域设置无关的方式使用 WMIC 获取当前时间戳。
我对此进行了大量搜索，但 none 我找到的答案有效或最终是相关的。我希望有人能提供帮助，我希望这可能是一个足够普遍的问题来帮助其他人。
