Exec task and "error :" in output

Question

Hi,

I just discovered a strange behavior of the exec task :

<Exec Command="echo error : "/>

will fail with code -1

and

<Exec Command="echo warning : " />

will print a warning.


Is it possible to disable this command output parsing ? I currently use ContinueOnError="True" but that modify my build logs.


Regards,

Hi Ant1,

By default, MsBuild will format the warnings and errors which Visual Studio can then display. We can ignore this beahvior in 3.5 by setting the IgnoreStandardErrorWarningFormat parameter to True. Please try something like the following:

<Exec Command="echo error:" IgnoreStandardErrorWarningFormat="true"/>

Hope this helps.
Best regards.

Oh, thanks a lot !

I am missing something in the msdn ? I don't see anything about it here : http://msdn.microsoft.com/en-us/library/x8zx72cd.aspx


Thanks again,

I have similar problem that I have narrowed down to a trivial C++ console program

#include <iostream>

int main()

{  std::cout << "error:" << std::endl; }

 

If run using Ctrl F5, or from the IDe Debug, start without debugging, this produces the expected output "error:".

 

But if run using a Post Build (or Custom ) command "$(TargetDir)$(TargetName).exe"
it outputs 

EXEC : error :

and exits

C:\Program Files\MSBuild\Microsoft.Cpp\v4.0\Microsoft.CppCommon.targets(183,5): error MSB3073: The command ""J:\Cpp\math_constants\Debug\error_test.exe"

C:\Program Files\MSBuild\Microsoft.Cpp\v4.0\Microsoft.CppCommon.targets(183,5): error MSB3073: :VCEnd" exited with code -1.

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped

How can I prevent this?

Where would I put

IgnoreStandardErrorWarningFormat="true"/

Thanks

PS I expect to have lots of projects and solutions with this problem.
