The text finder is a great tool to look for data generated by the build except
if the string you're looking for is in the build output itself. Then you can't
search for it.
In my particular case, the build succeeds on windows because the batch mechanism
hudson uses to start the build process on the box prevents the return code or
ERRORLEVEL I should say, to be bubbled all the way up to hudson.
Hence, my windows builds always seem to pass even though they may very well have
failed. The only option is to actually go ahead and look at the build log, which
is ok if you have a single build a day. In my case, there are now 8 boxes
building about 200 times a day, which renders the manual check not an option.
