Create an ant build and it works fine on master.
the output is as follows...

[ProjectName] $ cmd.exe /C ant.bat publish

but tie this build to a slave the output becomes

[ProjectName] $ ant publish

And the error stack trace...

If you attempt to do Runtime.getRuntime.exec("ant publish"); you get the same
issue. For some reason the ant invocation is not generating as ant.bat which is
what it needs to be generated as.
