即使jar文件存档失败,我也面临%errorlevel%返回0值的问题。
我想要实现的是在生产环境中存档日志文件。我使用ROBOCOPY命令将日志文件复制到一个单独的文件夹,并尝试存档这些日志文件。 “verify> nul”用于将%errorlevel%重置为0,因为robocopy会在执行后将值设置为1。
但是,当执行jar命令期间发生错误(即没有要归档的文件)时,%errorlevel%保持为0并且程序继续。

注意:从属性文件中读取Varible。第三方库不允许安装,因此我选择使用jar命令
任何提示如何检测是否发生错误?
感谢。

SETLOCAL EnableDelayedExpansion
...
IF !errorlevel! NEQ 0 GOTO ERROR
确保对范围内修改的括号范围内的所有变量执行此操作。
每当在括号范围()
内扩展变量时,变量将扩展到它们在范围开始之前的值,除非使用延迟扩展或变通方法进行扩展。
@echo off
setlocal EnableDelayedExpansion
set "x=0"
echo %x%
if 1==1 (
set "x=1"
echo %x%
)
endlocal

作为David方法的替代(使用延迟扩展)我支持+1,您可以使用 if errorlevel
命令相反。我会的。
if errorlevel 1 goto error
在 The Old New Thing 博客中阅读此Raymond Chen条目 ERRORLEVEL不是%ERRORLEVEL% http://blogs.msdn.com/b/oldnewthing/archive/2008/09/26/8965755.aspx。
然后尝试这段摘录..
robocopy %ORI% %DEST% *.log ....
if errorlevel 2 goto error
...
if exist *.log (
jar -cvMf ..
if errorlevel 1 goto error
for %%a in *.log do (
del %%a ....
if errorlevel 1 goto error
)
)
