如果jar文件的存档失败,如何检测错误?

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。

@ECHO off
SETLOCAL

ECHO [info] LogFileArchivaer Started at time %date% %time% ...
SET LOG_FILE_AGE_IN_DAY=7

REM Directory variable setting
FOR /F "tokens=1,2 delims==" %%G IN (config.properties) DO (

    IF "%%G"=="log.app.dir.ori" (
        IF NOT EXIST %%H\NUL (
            ECHO [error] Directory "%%H" not exist!
            GOTO ERROR
        )
        SET APP_LOG_DIR_ORI=%%H
    )

    IF "%%G"=="log.server.dir.ori" (
        IF NOT EXIST %%H\NUL (
            ECHO [error] Directory "%%H" not exist!
            GOTO ERROR
        )
        SET SERVER_LOG_DIR_ORI=%%H
    )
    IF "%%G"=="log.batch.dir.ori" (
        IF NOT EXIST %%H\NUL (
            ECHO [error] Directory "%%H" not exist!
            GOTO ERROR
        )
        SET BATCH_LOG_DIR_ORI=%%H
    )
    IF "%%G"=="log.app.dir.dest" (
        IF NOT EXIST %%H\NUL (
            ECHO [error] Directory "%%H" not exist!
            GOTO ERROR
        )
        SET APP_LOG_DIR_DEST=%%H
    )
    IF "%%G"=="log.server.dir.dest" (
        IF NOT EXIST %%H\NUL (
            ECHO [error] Directory "%%H" not exist!

    )
    IF "%%G"=="log.file.age" (
        SET /a LOG_FILE_AGE_IN_DAY="%%H"*1
    )

ECHO [error] Error Occurred, program exit at time %date% %time%!    
GOTO END

:COMPLETED
ECHO [info] LogFileArchivaer Completed at time %date% %time% ...

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。

答案 0 :(得分:2)

使用延迟扩展

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

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
   )
)
