CruiseControl.NET & batch's %ERRORLEVEL%

I wanted to do a very simple thing using CruiseControl.NET - have a batch file that does some work be executed in my project and if error level is not "0" fail the test.

I started by creating a very simple Project with the Exec task that execute batch file called BuildHub.bat (for the sake of demo):

<project name="HUB" queue="SR_GUI">
  <workingDirectory>c:\temp</workingDirectory>
  <artifactDirectory>c:\temp</artifactDirectory>
  <sourcecontrol type="nullSourceControl" />
  <triggers>
    <projectTrigger project="SP Build" />
  </triggers>
  <tasks>
    <exec executable="BuildHub.bat" />
  </tasks>
</project>

 

The batch looks something like this:

@echo off

echo provision drive

... some lines script ...

Echo Debug: Error level = %ERRORLEVEL%

 

I started to check the project by running it and although I knew it should fail (I saw the debug note about error level = 9002) it always reported as succeeded.

initially I tough that because I used last action of echo then it might reset the error level but this wasn't the case (validated by running manually)

To make a long story short the resolution was to simply put the following line at the end of the batch:

Exit /B %ERRORLEVEL%

As always I hope this save you some time
