从Windows批处理詹金斯和返回code [英] Jenkins and return code from windows batch

问题描述

我使用的作业（在Windows计算机上），一个詹金斯编译一些code通过蚂蚁不同的目标。
这样做，我包调用Ant目标一（视窗）批循环这样的范围内：

 关闭@echo
对于%%吨（目标1 TARGET2 target3）做（
  蚂蚁-f build.xml构建-DPARAM_TARGET = %%Ť
）
 

这是我的第一个想法......但是这codeS导致一个成功的构建，即使（例如）目标1失败。所以我把一些线路的Windows批处理构建步骤，以获得更多的概述。此外，我已经checekdout了code，以获得比詹金斯有我的本地机器一样workingspace并添加test.bat的检查Windows批处理code可以在所有的工作。

 关闭@echo
对于%%吨（目标1 TARGET2 target3）做（
  蚂蚁-f build.xml构建-DPARAM_TARGET = %%Ť
  回声ELVL：％ERRORLEVEL％
  IF NOT％ERRORLEVEL％= = 0（
    回声中止：％ERRORLEVEL％
    退出/ B％ERRORLEVEL％
  ）ELSE（
    回声继续：％ERRORLEVEL％
  ）
）
 

这个测试我的本地Windows机器上显示了预期的行为 - 在这里成功：

  BUILD SUCCESSFUL
总时间：3秒
ELVL：0
继续：0
 

和失败：

 构建失败
C：\\工作\\ ...
C：\\工作\\ ...总时间：0秒
ELVL：9009
中止：9009
 

这是詹金斯同样code做到这一点：

 构建失败
C：\\工作\\ ...
C：\\工作\\ ...总时间：4秒
ELVL：0
继续：0
 

使用谷歌为它揭示了一会儿，从调用Ant目标回报code未正确传递给Java enviornment从那詹金斯做后来电。我身边有使用呼叫或设置ERRORLEVEL = 1这样的事情，测试，但还没有找到一个soloution呢。

任何人有一个想法？
放环（target1-3）到系统Groovy脚本和手动喊得的CALLC - 做这项工作。

问候

解决方案

我觉得你的问题是因为你在一个for循环读取％ERROR_LEVEL％。

我认为你必须使用 SETLOCAL EnableDelayedExpansion

  

EnableDelayedExpansion：展开变量在执行时，而不是在分析时

（裁判是这里）

尝试做这样的事情：

  SETLOCAL EnableDelayedExpansion对于%%吨（目标1 TARGET2 target3）做（
   蚂蚁-f build.xml构建-DPARAM_TARGET = %%Ť
   回声ELVL：ERRORLEVEL！
   IF NOT！ERRORLEVEL！ == 0（
     回声中止：！ERRORLEVEL！
     退出/ B！ERRORLEVEL！
   ）ELSE（
     回声PROCEED：ERRORLEVEL！
   ）
）
 

它没有解释为什么它运行在您的计算机上...也许是因为EnableDelayedExpansion在您的DOS窗口已经设置。

修改

在批处理文件：

当code解析
• ％VAR％将扩大（即执行前！）


• ！无功！执行code时，将扩大

既然你是在一个循环：％ERROR_LEVEL％一度扩大（即之前先执行）。但是，你需要的是重新展开 ERROR_LEVEL 每次迭代，这就是的！ERROR_LEVEL！语法。<目的/ p>

I using a Jenkins (on a windows machine) job to compile some code for different targets via Ant. For doing so, I wrap the call to the ant target within a (windows) batch loop like this:

@echo off
for %%t in (target1 target2 target3) do (
  ant -f build.xml build -DPARAM_TARGET=%%t
)

That was my first idea ... but this codes leads to an successful build even if (e.g.) target1 failed. So I put some more lines to the windows batch build step to get more overview. Also I have checekdout the code to get the same workingspace than Jenkins has to my local machine and add an test.bat to check the windows batch code can work at all.

@echo off
for %%t in (target1 target2 target3) do (
  ant -f build.xml build -DPARAM_TARGET=%%t
  echo ELVL: %ERRORLEVEL% 
  IF NOT %ERRORLEVEL% == 0 ( 
    echo ABORT: %ERRORLEVEL%
    exit /b %ERRORLEVEL%
  ) ELSE (
    echo PROCEED: %ERRORLEVEL%
  )
)

Testing this on my local windows machine shows the expected behaviour - here on success:

BUILD SUCCESSFUL
Total time: 3 seconds
ELVL: 0
PROCEED: 0

And on failure:

BUILD FAILED
C:\Work\...
C:\Work\...

Total time: 0 seconds
ELVL: 9009
ABORT: 9009

The same code on Jenkins do this:

BUILD FAILED
C:\Work\...
C:\Work\...

Total time: 4 seconds
ELVL: 0
PROCEED: 0

After using google for a while it reveals, that the return code from calling the Ant target is not properly passed to the java enviornment wherefrom Jenkins do the calls. I have tested around using "call" or "set ERRORLEVEL=1" something like this, but haven't found a soloution yet.

Anyone has an idea? Put the loop (target1-3) into a system groovy script and hande the callc manually - does that work?

解决方案

I think your problem is because you read %ERROR_LEVEL% in a for loop.

I think you must use setlocal EnableDelayedExpansion

EnableDelayedExpansion : Expand variables at execution time rather than at parse time.

(ref is here)

Try to do something like this :

setlocal EnableDelayedExpansion

for %%t in (target1 target2 target3) do (
   ant -f build.xml build -DPARAM_TARGET=%%t
   echo ELVL: !ERRORLEVEL! 
   IF NOT !ERRORLEVEL! == 0 ( 
     echo ABORT: !ERRORLEVEL!
     exit /b !ERRORLEVEL!
   ) ELSE (
     echo PROCEED: !ERRORLEVEL!
   )
)

It don't explain why it runs on your computer... maybe because the EnableDelayedExpansion is already set in your dos windows.

EDIT

In batch-file :

• %var% will be expanded when the code is parsed (i.e. before execution !)
• !var! will be expanded when the code is executed

Since you are in a loop : %ERROR_LEVEL% is expanded once (i.e. just before first execution). But what you need is to re-expand ERROR_LEVEL for each iteration and that's the purpose of !ERROR_LEVEL! syntax.
