Question

We have a process that runs prior to our nightly builds. If the process fails it generates a text file. All I need to do is check to see if the file exists, and if it does, cause a failing MSBuild.

I currently have tried the following:

<CreateProperty Condition='Exists('C:\Process\Fail.txt')'       Value='false'>   <Output TaskParameter='Value' PropertyName='ProcessTestPassed'/> </CreateProperty> <Message Text='Process did not pass' Condition='Exists('C:\Process\Fail.txt')' ContinueOnError='false' />  <ReadLinesFromFile File='C:\Process\Fail.txt'                  Condition=''$(ProcessTestPassed)'=='false'' ContinueOnError='false' >   <Output TaskParameter='Lines' ItemName='FileContents' /> </ReadLinesFromFile> <Message Text='FileContents: $(FileContents)'  Condition=''$(ProcessTestPassed)'=='false'' ContinueOnError='false' /> 

Which gives a passing build with this output:

Task 'CreateProperty' Done executing task 'CreateProperty'. Task 'Message'   QAWizardProTestPassed did not pass Done executing task 'Message'. Task 'ReadLinesFromFile' Done executing task 'ReadLinesFromFile'. Task 'Message'   FileContents:  Done executing task 'Message'. 

I know the above is probably overkill, but I just need something working! What am I missing here?

As noted by @dprice in his comment, the best solution for this would be:

<Error Condition='Exists('C:\Process\Fail.txt')' Text='Process did not pass!' />
